Abstract: A device for forming a moving web of laminated composite material having window portions therein from a moving continuous web of plastic film material and a moving continuous web of paper material. The device comprises cutter means for repeatingly cutting spaced apart perforated window patterns in the paper web and a wetting means for wetting the film web at spaced apart target areas having shapes substantially identical to the perforated window patterns. The device further comprises phasing means having both a coarse mode and a fine mode of operation for providing accurate registry of the perforated window patterns and the wetted target areas. A wetting synchronization means is also described which synchronizes the wetting means with the film target areas whereby the target areas and only the target areas are wetted by the wetting means. Means for removing a paper chad portion from the perforated window patterns subsequent to lamination is also described.

Abstract: A laminating apparatus for laminating extensible plastic film material to a paper backing material to form a laminated composite. The apparatus comprises mechanical stretch control means for controlling the stretch or relaxation of the film material prior to lamination with the paper material. The apparatus also comprises means for monitoring the amount of film stretch in the laminated composite and providing data therefrom to a data processing unit which provides control signals to operate the mechanical stretch controlling means.

Abstract: Apparatus is disclosed for making ends for metal or composite can bodies, which ends are first partially formed in a press to a cup-shaped configuration including a peripheral skirt and are then fed to a curling machine in which the skirt is contoured to facilitate application of the end to a can body. The press has a vertically reciprocable slide or slides which, together with an opposed portion of the press frame, support pairs of cooperable dies for blanking and partially forming can ends from sheet material fed horizontally into the press. Thereafter, the partially formed can ends are displaced into a horizontal plane vertically spaced from the sheet feed line, and a kicker member associated with each die set is operable in coordination with slide movement to impact against and propel the partially formed can end laterally and into a guide chute leading either to a curling machine or to an endless conveyor by which the partially formed can end is delivered to a curling machine.

Abstract: Apparatus is provided for forming a chime bead adjacent the closed end of a seamless cup-shaped metal can body and a plurality of peripheral beads intermediate the opposite ends of the can body. The apparatus includes a plurality of beading spindles receiving and supporting can bodies for movement along an arcuate path. The beading spindles are provided with beading tool portions corresponding to the chime and intermediate beads to be formed on a can body. The frame supports axially offset and sequentially arranged outer beading rails positioned along the arcuate path of spindle movement. During movement of the spindles along the path between input and output stations of the apparatus, can bodies on the spindles are rotated about the spindle axes and, as each can body moves past the outer beading rails, the beading tool portions of the spindles and the outer beading rails cooperatively engage a can body therebetween to sequentially form first the chime bead and then the intermediate beads on the can body.

Abstract: Apparatus is disclosed for detecting flaws in sheet material of the character which increase the surface height of the sheet material. The apparatus includes a pair of horizontally parallel driven lower rolls and three upper rolls each mounted on a corresponding pivotal bracket. Two of the upper rolls are associated with one of the lower rolls and are axially spaced apart therealong, and the third upper roll is associated with the other lower roll and positioned therealong to span the space between the other two upper rolls. Each of the upper rolls is rotatably supported by the corresponding bracket for pivotal movement toward and away from the lower roll. Each upper roll bracket is provided with a pair of adjustable stop screws, one adjacent each of the opposite ends of the corresponding upper roll, and each adjustable stop screw carries a switch actuator screw which is adjustable relative to the stop screw.

Abstract: A mechanism is provided for advancing articles step by step between work stations of a press. The mechanism includes a pair of bracket assemblies mounted on opposite sides of the press frame and provided with feed bar support assemblies including members supporting a pair of parallel feed bar-feed finger members for longitudinal and lateral reciprocation to achieve article transfer. The bracket assembly includes a first portion fixed on the press frame and a second portion which carries the corresponding feed bar support assembly and which is pivotal relative to the first bracket portion between use and non-use positions. The drive arrangement for the reciprocable feed bar support members includes portions pivotal with the second bracket portion. The feed bar-feed finger members are detachable, thus enabling the second bracket portions and corresponding portions of the drive arrangements to be pivoted to the non-use position to facilitate access to the press.

Abstract: An article transfer mechanism is provided comprising parallel spaced apart feed plates reciprocable in the direction between the opposite ends thereof and carrying a plurality of laterally opposed article engaging feed finger members. Each feed finger member is supported for reciprocation laterally relative to the corresponding feed plate, and the feed plates support corresponding cam rods displaceable therewith and relative thereto in the direction of reciprocation of the feed plates. A cam and lever arrangement reciprocates the feed plates to displace the feed finger members longitudinally, and a second cam and lever arrangement reciprocates the cam rods to displace the feed finger members laterally inwardly and outwardly relative to the feed plates.
