According to yet another aspect of the present invention there is provided a pastry product comprising a pastry sheet unit and a film sheet unit which are adapted to be rolled together so that in the finished -roll the finished sheet unit is substantially interposed between the adjacent layers of the pastry sheet unit, the film sheet unit and the pastry sheet unit having a leading edge and a trailing edge characterised by the leading edge of the film sheet unit overlying and extending rearwardly of the leading edge of the pastry sheet unit prior to being rolled together.
In the particular form of the invention in which the leading edge of the film sheet is displaced rearwardly of the leading edge of the pastry sheet so that when rolling is commenced the leading, edge of the pastry sheet will initially contact a portion of the pastry sheet. When used in connection with the rolling means described above this provides sufficient frictional contact for rolling to continue.
By the term film sheet is meant any suitable interleaving material such as for example wax paper polymeric material or the like.
Preferred embodiments of the invention will hereinafter be described with reference to the accompanying drawings, in which: Figure 1 is a schematic side elevation of apparatus according to the invention,
OMPI °
Figure 2 is a plan view of the apparatus shown in Figure 1,
Figure 3 is a schematic side elevation of apparatus for forming the sheet products into a roll, Figure 4 is a plan view of the apparatus shown in Figure 3.
Figures 5 and 6 are more detailed views of the transfer means which form part of the apparatus shown in Figures 1 and 2. Figures 7 to 9 are more detailed schematic views of the delivery means which form part of the apparatus shown in Figures 1 and 2? and
Figures 10 to 12 are schematic views showing the formation of the pastry product according to the invention.
As best seen in Figures 10 to 13 the pastry product of the present invention comprises a pastry sheet unit 71 and a film sheet unit 72 which are adapted to be rolled together to form a finished roll 70. Each sheet unit 71 and 72 has a leading edge and a trailing edge 75 and 76 and 77 and 78 respectively. When rolled together the film sheet unit 72 is interposed between adjacent layers of the pastry sheet unit 71 so as to inhibit the adjacent layers from sticking together. In the product of the present invention, prior to rolling, the leading edge portion 79 of the film, sheet unit 72 is displaced rearwardly from the leading edge 75 of the pastry sheet unit 71 and rolling is instigated' from the leading edges of the sheets. As shown it is preferable that the trailing edge of the film sheet unit is disposed rearwa-rdly relative to that of the pastry sheet unit.
Thus by-rolling in the manner shown it is possible to form a roll 70 in which the last surface portion of the pastry sheet unit is overlaid by the trailing portion of the film sheet unit. Referring to Figures 1 to 5 of the drawings, pastry material in the form of a continuous sheet 60 having side edges 61 is fed to film applying station 5 via a conveyor (not shown) . At the film applying station 5 a roll of film material 20 is mounted and arranged to— e-=s fed to the sheet of pastry 60 through the film guide and application device 15 which comprises suitably arranged drive rolls and guides. The sheet of pastry 60 is transferred through the applying station 5 via transport means 8 in the form of a conveyor 9. Thus the pastry material and film applied thereto are at this stage in the form of continuous sheets 60 and ?0 from which the sheet units are formed. The leading and trailing edges of each sheet unit are at this stage defined by the parallel side edges 61 and 21 of the continuous sheets. Although many different types of film material could be suitable for the product a preferred material is a plastic film termed CRISPY-WRAP (Trade Mark) .
The drive rolls and guides 15 are so arranged so that the edges 21 of the continuous film sheet 20 are offset relative to the side edges 61 of the continuous pastry sheet 60 thereby enabling the sheet units and their relative disposition as described above to be achieved. Preferably since the overlap of the trailing edge portion of the continuous sheet unit is wider than the portion of the leading edge thereof relative to that
of the pastry sheet the roll of film sheet is slightly wider than the continuous sheet of pastry.
Preferably water is applied to the surface of the pastry sheet prior to applying the film sheet 20 thereto the water tending to enhance adhesion between the two sheets. The water may be applied using a water roller however in a preferred form a plurality of nozzles (not shown) are arranged at the station just upstream from the drive rolls and guides 15. Cutting means 40 in the form of a powered guillotine separates the continuous sheets into discrete sheet units 71 and 72 of selected size. The guillotine is disposed downstream of the station 5. Suitable control means is provided to control operation of the transport conveyor 9 and the guillotine.
The separate sheet units 71 and 72 are then transferred to a spacer means in the form of an accelerating conveyor belt 35 which spaces adjacent sheets apart at a desired distance. Such a belt is of conventional form and it is not necessary to describe in detail here.
The separate sheet units are then selectively transferred to delivery means in the form of conveyors 46 and 48 whose direction of travel is normal to the direction of travel of the transport conveyor . The delivery conveyors 46 and 48 are mounted on a carriage member 49 which is adapted to reciprocate in a direction parallel to the direction of travel of the feed conveyor and which is operable to move at substantially the same speed as the conveyor 35 so that the sheets of material
" QRE l OMPI'
can be transferred thereto with little or no relative movement between the two conveyor systems.
Referring to Figures 7 to 9 which show one of the delivery conveyors 46 comprises a conveyor belt 50 which is driven by motor 51. The conveyor belt 50 is mounted on a carriage member 49 which includes a pair of guides 52 which run on tracks 56 supported by frame 58. A power screw 53 is operatively connected to the carriage by ball nut assemblies 54. The power screw is driven by motors 55 and 59 one motor for use when the pastry products are transferred onto it from the conveyor 35 and the other for returning it to its initial position. The motor which returns the carriage to its initial position is adapted to move it much faster than the other motor.
Transfer means comprising a gate 36 is operable via a photo-electric counter to permit the transfer of a select number of sheets to delivery conveyor 46 and thereafter enable a further select number of sheets to be transferred to delivery conveyor 48.
The gate 36 is operable for movement between a lowered position in which the sheets pass from conveyor 35 to conveyor 39 from which the sheets are transferred to delivery conveyor 48, and an upper position in which the sheets are transferred to delivery conveyor 46. The gate 36 is actuated by solenoid 37 and lever 38. The sheets when positioned on the delivery conveyors 46 and 48 are now arranged with their leading edges facing the direction of travel. The delivery conveyors transfer the sheets to roll-up apparatus 85.
The roll-up apparatus comprises a work station which includes a conveyor belt 86 a leading edge pick-up device 87 and a drag inducing member 88. Thus as the leading edge of the pastry material approaches the station a series of fingers which are pivotally mounted pick-up the leading edge so that it is turned back on itself whereafter this portion engages the drag member which is in the form of a chain wire mesh which thereby at least partially rolls the two sheets together. The partially rolled product is then transferred to a further station where rolling of the product is completed. After rolling is completed the product can be transferred to a packaging station where it is placed in a package.
