Abstract
Dry transfer word sets are produced using a tape comprising a flexible backing tape (1) and a translucent or transparent carrier tape (4) having therebetween a shearable dyed or pigmented layer (2). When raised characters (6) are successively pressed against the tape, the adhesion of the shearable layer material to the carrier tape (4) increases where the pressure is applied. Thus when the backing and carrier tapes are separated in the areas against which the raised characters (6) have been pressed, the shearable layer material is retained on the carrier tape (4), while the remaining shearable layer material is retained on the backing tape (1). The shearable layer material is transferred from the carrier sheet (4) on to a receptor surface (5) by rubbing on the rear of the carrier tape (4). <IMAGE>
Description
SPECIFICATION
Production of dry transfer word sets
This invention relates to the production of dry transfer word sets.
In recent years a variety of dry transfer materials has been developed. Generally they consist of a transparent or translucent carrier sheet bearing a plurality of symbols on one side, which can be transferred from the carrier sheet to a desired receptor surface.
Dry transfer materials have been made for many years by standard printing techniques, usually silk screen printing. For economic reasons, due to the inflexibility of the system, commercially sold dry transfer sheets comprise a plurality of characters, e.g. numbers, indicia, images, arranged on a single transfer sheet. In order to build up a word set therefore the operator has to transfer each character separately from the transfer sheet to the desired receptor surface. Thus he has separately to position each character on the receptor surface and rub the back of the carrier sheet of the dry transfer to effect the transfer of the character to the receptor surface. Very satisfactory results can be achieved in this manner but considerable skill and eye is required to ensure accurate positioning and alignment of the characters of the word set built up on the receptor surface.
For the sake of clarity it is observed that by the word "word set" used herein is meant any desired combination of characters, whether letters, numbers or symbols.
It is known to produce word sets in the form of tape labels. Such tape labels are produced by the successive application of raised characters against a tape, whereby under the influence of pressure on the tape the form of the character becomes visible in the tape. Various so-called embossing machines are marketed, e.g. under the Trade Marks DYMO and KROY, and have found use in the home and in the office.
Labelling tapes may thus be used in a simple hand held machine in which the tape is fed between two embossing dies which are pressed together to emboss the desired letter shape on the tape. The tape is then advanced, the next character is chosen and embossed on to the labelling tape to form the character in the tape. In this way word sets in which the characters are correctly spaced and aligned are built up. The label formed is then cut off. The tape consists of two layers held together by a tacky pressure sensitive adhesive.
After the tape bearing the word set has been cut off, one layer is peeled off and the other layer which constitutes the label on the desired surface is adhered to the required receptor surface.
According to the present invention there is provided a tape for use in the production of a dry transfer word set which tape comprises a flexible backing tape, and a transparent or translucent carrier tape having therebetween a shearable dyed or pigmented layer, whereby under the influence of applied pressure the adhesion of the shearable layer material to the carrier tape increases such that, when the backing and carrier tapes are separated, in areas to which pressure has been applied shearable layer material is retained on the carrier tape, the remaining shearable layer material being retained on the backing tape and the shearable layer material on the carrier tape being releasable therefrom on to a receptor surface by rubbing on the rear of the carrier tape.
The tape according to the present invention can be used in the production of dry transfer word sets in a manner analogous to the building up of labels on embossing tapes. Thus the desired characters are successively pressed against the tape (and the tape is advanced in between) until the desired word set has been built up. In the areas to which pressure has been applied by means of the raised characters then the shearable layer material adheres more strongly to the carrier tape. When the desired word set has been built up, the tape is cut and the backing and carrier tapes are then separated to leave the word set transferably adhered to the carrier tape. The word set is then applied to the desired receptor surface from the carrier tape by simply laying down the tape and rubbing over its back to effect transfer to the receptor surface.In this way the characters of the word set may already be properly aligned on the carrier tape and accordingly no skill on the part of the operator is required to ensure accurate alignment and positioning in the final product.
The invention also provides a method of producing a dry transfer word set which method comprises, at predetermined spacing and alignment, pressing raised characters corresponding to the characters of the desired word set against the backing tape of a tape according to the present invention and subsequently separating the backing and carrier tapes.
Suitably the characters of the word set are pressed against the tapes according to the present invention in an entirely analogous manner to that whereby raised characters are pressed against tapes in conventional embossing tape labelling machines. Indeed, the tapes according to the present invention can be used in conventionally marketed embossing labelling devices in which the female dies have been filled so that they present a flat anvil surface for the application of pressure in each case. The tape advance and tape cutting mechanisms for advancing the tape as successive letters are imaged on to it and for severing the imaged portion of the tape are well known from the commercially sold devices and from the patent literature and are not therefore described further here.Thus the operator chooses the first character, e.g. displayed around a wheel on a labelling device, the raised character form is pressed against the tape, the tape is advanced in the machine, the next character is chosen, the raised character form pressed against the tape and so on until the desired word set has been built up.
The tape according to the invention must be formulated so that, in the areas to which pressure is applied, the shearable layer material is released from the backing tape to be retained on the carrier tape, while on the other hand the material retained on the carrier tape is then transferable to the desired receptor surface. In addition the carrier tape needs to be transparent or translucent so that when the word set has been built up it can be properly positioned on the receptor surface. Suitably the carrier tape may be of plastics material, for example polyester e.g. polyethylene terephthalate, or polyethylene. The backing tape may be of any suitable material. It may be provided with a release coating to ensure good release of the shearable layer material under pressure. For example silicone-coated paper may be used.
The shearable dyed or pigmented layer must be sufficiently adhesive for the final word set to adhere to the desired receptor surface while being released from the flexible backing tape when the backing and carrier tapes are separated. In general layers shear well if the strength or quantity of binder is kept to the minimum required just to hold the layer in place on the support, and if ingredients of low cohesive strength such as waxes are incorporated.
The tape according to the present invention may be prepared by coating the flexible backing tape material with shearable layer composition, drying the layer so obtained and then applying the carrier tape material thereover.
The invention is further described, with reference to the accompanying drawing, which illustrates schematically the production of word set according to the present invention.
Referring to the drawing, there is used a tape according to the present invention comprising a flexible backing tape 1 and a transparent or translucent carrier tape 4, e.g. of polyethylene terephthalte or polyethylene. Between the backing and carrier tapes there is a shearable dyed or pigmented layer 2. A raised character 6, e.g. in a hand labelling device, is pressed against the flexible backing tape 1 of the composite tape in step A. The backing tape and carrier tape are then separated in step B causing shearing of the dyed and pigmented layer 2 with the result that in the areas to which pressure has been applied by means of character 6 the shearable layer material is released from the backing tape 1 and is retained on the carrier tape 4, the remainder of the shearable layer material being retained on backing tape 1.In step C the character is then transferred from carrier tape 4 by means of rubbing the back of carrier tape 4 on to the desired receptor surface 5.
Example
A tape was prepared by screen printing on to siliconised vegetable parchment (46 gsm ex Leonard Stace) a pigmented shearable coating composition was formulated as follows:
% by weight
Carbon Black (Elftex 150
ex Charles Tenant) 7
Ethyl hydroxy ethyl
cellulose (EHEC XLV ex
Hercules Chemicals), 25% by weight in a solution
of 35% by weight aromatic
hydrocarbon fraction boiling
between 168 -200 C (Aromasol
H ex Womersley-Boome
Chemicals) and 40% by weight butyl oxitol (Alcohols
Limited) 56
Terpene Resin (Piccolyte A.
125 ex Wedge Chemicals),
65% by weight in aliphatic hydrocarbon solvent (Isopar G ex Esso) 10
Polyethylene wax (AC 1702
Wax ex Allied Chemicals),
50% by weight in Isopar G. 27
The coated layer was dried by means of hot air and provided thereover with a carrier of transparent polyester film, 80 microns in thickness (Melinex ex i.C.I.).
The material so obtained was cut into strips of the desired width and fed through a modified hand held
Dymo labelling device which had been modified as described above to provide a substantially smooth impression surface.
A word set was built up by using the device successively to press a raised letter against the tape and then advance the tape ready for the next letter. This served to transfer the coating imagewise from the siliconised vegetable parchment paper on to the polyester carrier so that when the siliconised vegetable parchment paper and polyester carrier were pulled apart the word set remained in the polyester carrier tape.
The word set was then transferred to a receptor surface by the application of pressure from a stylus to the back of the polyester carrier. In this way there is transferred the desired legend already correctly spaced.
