Abstract

1,250,789. Checking bags in bag making machines. WINDMOLLER & HOLSCHER. - 5 Nov., 1968 [6 Nov., 1967], No. 52325/68. Addition to 1,122,788. Heading B5D. The machine for making cross-bottom bags described in the parent Specification is modified by providing photo-detectors for receiving reflected light, which co-operate with stationary reflecting elements 306 which enter between the upper ply of a bag workpiece 316 and the inner half 317 of the bottom. The reflecting elements 306 are mounted on a plate 301 mounted parallel to the plane of conveyance at a distance above this plane exceeding the maximum thickness of the bag workpieces. A guide element 313 is, as shown, connected to the plate 301 by springs 311 which bias the guide element lightly downwardly so that its leading edge 314 engages the workpiece and enters between the body and the inner half 317 of the bottom as the workpiece travels in the direction of arrow 315. The ends 319, 320 of the guide and the plate are bent upwardly to ensure that the workpiece 316 reliably enters under the reflecting elements. In a modification the guide member is hinged to the plate and engages the workpiece under gravity. Specification 1,209,938 is referred to.
