Description

  The present invention relates to a slitter that cuts a side portion of a wall covering in advance when applying glue to the wall covering with an automatic wallpaper pasting machine, and relates to an automatic wallpaper pasting machine equipped with the slitter.

  Currently, affixing of wall coverings to interior walls in interior construction of buildings is performed while applying glue continuously to sheet-like wall coverings using a dedicated wallpaper pasting machine at the interior work site. It has become common. As a general configuration of this wallpaper gluing machine, a gluing machine main body mainly composed of an upper structure and a lower structure in which a plurality of rollers are arranged is placed on a pedestal supported by legs. The sheet-like wall covering material (hereinafter also referred to as a cross) sandwiched between the upper and lower structures is conveyed by a roller, and the glue is picked up from the glue tank by a glue scraping roller supported in the glue tank, and used as a gluing roller. It is transferred and applied to the back surface of the cloth by this gluing roller.

  There are two types of wallpaper pasting machines: manual type and automatic type. As an example of the specific configuration, the upper part is placed on the lower structure with the cloth fed from the roll roll placed on the front of the main unit. The structure is closed and a cross is sandwiched between predetermined rollers of the lower structure and the upper structure. In the manual type wallpaper pasting machine, the operator holds the tip of the cloth by hand and pulls it forward to rotate a part of the roller while rotating the other roller in conjunction with the gear. In an automatic wallpaper pasting machine, a roller of a predetermined roller is generally connected to a driving source such as an electric motor and rotated so that other rollers also rotate in conjunction with each other through a gear.

  In any of the gluing machines, the glue that has been pulled up and transferred from the glue tank in the middle of conveying the cloth from the rear side to the front side of the gluing machine body by the rotation of the roller is transferred from the roller near the top of the gluing roller. The glue is transferred to the back of the cloth, and the cloth is sent out from the front with the glue applied. The length of the glued cloth is displayed using one of the interlocking rotating rollers as the measuring roller. ing. In particular, the automatic wallpaper pasting machine has a function of presetting the length of the cloth to be glued in advance and automatically stopping when reaching a predetermined length. In addition, when a sensor such as a photoelectric signal element is installed in the cloth transport path to detect a cross paper break, or when a detection signal from the measuring roller is no longer detected, a terminal that identifies the terminal end of the cloth A wallpaper pasting machine provided with a part detection means has also been proposed (see, for example, Patent Document 1).
