Abstract

526,676. Making paper and like bags. ROBINSON. F. G., and PAPER SACKS, Ltd. Feb. 21, 1939, No. 5792. [Class 94 (ii)] In the making of multi-ply paper &c. bags, such as those described in Specifications 443,920 and 443,950, the flat tube or bag A is arched at its ends B during the opening operation to cause the inner plies to lie against the outermost ply without the use of adhesive. The opening may be effected by suction devices 3, 4 on the upper side and a third 6 on the lower side. After suction has been applied, 3 and 4 are raised and 6 lowered to open the tube by cams 34, 19 and linkwork 25 ... 33 and 13 ... 18. The opening is completed by a pair of blades 37, 38 inserted into the tube while they are closed and then expanded to the position in Fig. 6 by levers 39, 40 coacting with fixed cams 43, 44, and activated by a cam 51 through lever 47, 49.
