Filed: 1944-10-02
Abstract: 586,653. Bag making. WALSH, J., and ILLING WORTH, W. Oct. 2, 1944, No. 18819. [Class 94 (ii)] The seams of bag tubes, especially those made of cellulose acetate or like material, in which adhesive may, or may not, be used, are sealed by electricallyapplied heating means, and severed by knife and beater mechanism 12, 13, 14. The bag material passes through the usual folding means 2, around an interior former plate 3 which has a heatretaining plate 4 below the upper face or side of the bag tube. An electrically-heated plate 5 is mounted above the plate 4, and held by link 6 on a bar 7 adjustably secured by a set screw 7a on a fixed bracket 7b. The forward end of the plate 5 is pivoted to a lever 8 having a handle 8a. A spring 10 presses the plate 5 into contact with the bag tube seam. The rear end of 5 is slightly raised. Depressing the handle 8a against the spring 10 causes the plate 5 to lift. After passing through draw rolls 11, the tube is severed. The edge 12 of the former plate 4 is serrated and turned down so that the points of the serrations engage the inside of the lower surface of the tube when swept by the usual beater 13 during the revolution. Above the upper surface of the tube a fixed blade 14 is mounted on a cross bar 15 and, in plan, is bowed or formed with an an open-V angle. The edge has teeth 14a, the edge being preferably of arcuate form in front elevation. This causes severance of the tube to commence from the outer margins, and progress inwards. A series of spring fingers 16 hold the surface of the tube on the former plate under the upward action of the beater 13. The end folding operation may be effected by the usual dipper and rollers after, or concurrently with the application of adhesive to the exposed lip area. Heat may be used on the end closure. The bags may be block-bottomed in the normal way, or electrical-heated irons may be used. The adhesive may have a base of the same, or similar material, of that used for the tube.
