Abstract
345,161. Making paper bags. FISCHER, G., 25, Detmolderstrasse, Bielefeld, Germany. June 2, 1930, No. 16991. [Class 94 (ii).] Relates to machines for making flat paper bags from either tubular blanks or tubular webs in which the upper layer of a blank is carried around a roller m by a pin f whilst grippers d operating through thumb notches hold the lower layer to a folding cylinder c provided with lateral grippers e which, aided by a creaser blade g on the roller m, determine the line about which end folding is effected, the bag end being opened to diamond form by a nose h and presser plate r and pasted by a roller j, having blades k which form the folding creases, prior to a turning member n folding over the rear flap before a stationary blade s completes the end folding. According to the invention the gripper or grippers d are so arranged that bags with either folded bottoms as in Fig. 9 or crossed bottoms as in Fig. 12 may be made. The bags drop from the folding cylinder on to a conveyer moving continuously or intermittently longitudinally or transversely of the direction of the machine and lie on it either singly or with the bottom of one bag on the back of an adjacent one. The other end of the bag may be similarly closed except for the provision of a filling valve.
