Card Feed

A card feed and transport mechanism including a hopper 1, a picker knife 2, accelerator rolls 3 and transport rolls 4 permits feed capacity in excess of that possible without the acceleration rolls.

The picker knife 2 feeds cards 5 singly from the hopper and accelerates them from zero velocity V to a velocity V which is the maximum velocity which may be imparted by the picker knife. Acceleration rolls 3, operating initially at velocity V(m) ,engage a card 5 as its leading edge emerges from a hopper throat 6. The rolls 3 are then accelerated to a velocity V(c) which is the constant velocity of transport rolls 4 which receive the card from the rolls 3.

The rolls 3, alternating in speed between V(m) and V(c), take cards from the hopper at a faster rate than that possible by use of only the picker knife and rollers operating at a constant velocity.
