Abstract A device for feeding, scoring and stacking cards. In the feeding device each card is fed from a stack onto a moving platform, the trailing edge of the stack being shuffled by passing over a contoured vertical plate. In the scoring device the card passes between a circular blade and a cylindrical follower mounted on a base of large mass and vertically adjustable on the base. In the stacking device a photoelectric beam traverses the line of travel of the cards and when the beam is interrupted it actuates drive means for moving a conveyor which thus moves intermittently to receive the cards in overlapping relationship. In another aspect the stacking device has two conveyors receiving the cards but with opposite slopes, and a pair of opposed nozzles selectively directing an air stream across the line of travel of the cards causes them to be directed onto either one of the two conveyors.
A device for scoring a card, comprising: a circular knife mounted on a first rotatable shaft; a cylindrical follower mounted on a second rotatable shaft and located adjacent the knife, the axis of the follower being parallel to the axis of the knife, the second shaft being mounted on a base of large mass and being adjustable on the base to vary the gap between the knife and the follower; and roller means rotatable to move the card through the gap between the knife and the follower; said first and second shafts being preloaded in journal bearings.

Claim 3
Dependent Claim
26 words
A device as claimed in claim 1 in which the first shaft and the roller means are synchronously rotatable and the second shaft is freely rotatable.
Claim 4
Dependent Claim

Claim 5
Dependent Claim
85 words
A device as claimed in claim 1 in which the rollers comprise a pair of cylindrical grip rollers located one on each side of the first shaft and parallel therewith, and a plurality of disc guide rollers mounted on a pair of further shafts located one above each shaft roller, the guide rollers being adjustable laterally along the further shafts and the further shafts being adjustable vertically with respect to the grip rollers to vary the gap between the disc rollers and the grip rollers.
