Title: An improved container-forming machine
IPC: B31B3/28
Filed: 1951-11-01
Abstract: 704,369. Making cartons. ARNOLD, J. C. (Pneumatic Scale Corporation, Ltd.). Nov. 1, 1951, No.25613/51. Class 18 Pre-cut and scored blanks are folded to U-shape prior to being wrapped round mandrels mounted radially on a turret. The blanks 16 are fed from a hopper by known means including suction grippers 30, to rollers 24, 26 which forward them to parting rollers 52, 54, 56. Rollers 66, 68 feed them along rails 70 to a stop 72 against which they are aligned by reciprocating fingers 76. A vertically reciprocating plunger 74 forces each blank between a pair of the rails 70 to fold it to U- shape and deposit it on rails 138, 139. A pusher 142 reciprocating on rods 146, 148, and having elements 140, 141 for maintaining the blank in U-shape, forces the latter between folder blades 164, 166 and on to a platform 162. The platform 162 rises to press the blank against the mandrel 10 and the blades 164, 166 move upwards to wipe the sides of the U against the mandrel. The final folding of the upper edges of the blank over the top of the mandrel is carried out by known arcuate folders (not shown) pivoted to sweep over the top of the mandrel. The longitudinal carton seam is consolidated by a presser in known manner. The preliminary folding to U-shape enables a standard size machine to produce oversize cartons. The former 10 may carry an inner liner wrapped round it prior to the wrapping round of the blank. Specification 354,879 is referred to.
