FIG. 25 is a schematic wiring diagram of the control mechanism shown in FIGS. 4 and 6.
In general, the present invention contemplates a container forming machine for producing individual containers from prescored blanks of container forming material. The invention is herein illustrated as embodied in a container forming machine of the type having a plurality of intermittently movable horizontally disposed and radially extended forming blocks or mandrels about which the blanks of container forming material are wrapped to produce the container and, except as to such details as are hereinafter pointed out, the illustrated container forming machine may comprise any of the usual forms of such apparatus now upon the market. In the operation of such prior container forming machines, a blank of the material is wrapped about a forming block at one station of operation and adhesively secured along a longitudinal overlapping side seam to produce a tubular container having portions thereof extended beyond the end of the block. At a succeeding station of operation, the extended portions are folded over the end of the forming block in overlapping relation and adhesively secured together to provide a bottom closure. At a subsequent station of the machine, pressure is applied to the end closure to set the seal, and at a final station of operation the completed carton is stripped from the forming block and discharged onto a conveyor for delivery to a package filling and weighing machine.
Such prior container forming machines, known in the trade as a double package maker, as typified in the United States patents to John G. Vergobbi, Nos. 2,533,642 and 2,364,406, are arranged to form a lining bag about the forming block at one station of operation, and then wrap a carton blank about the lining on the block at a subsequent station of operation to form a lined carton. Such prior machines are designed to form one size of container only on one machine so that a second machine is required to produce containers of a dilferent size.
In accordance with the present invention, provision is made for producing two different sizes of individual or unlined containers on one machine with a minimum of interchangeability of parts to produce one or the other size of container. In the illustrated container forming machine, which has eight stations, provision is made for forming one size of container at station 1 where a blank is wrapped around a forming block to form a tube with an adhesively secured side scam, the extended portions of the tube being folded and adhesively secured at station 2. Stations 3 and 4 are similar to stations 1 and 2 except that they are arranged to form a different size of container. Station 5 comprises an end pressing station which is common to both sizes; station 6 is idle; station 7 com-
