Abstract: 1341681 Feeding sheets EL CU SpA 17 Nov 1972 [18 Nov 1971] 53154/72 Heading B8R When the leading edge of an open bag is sensed at 20 as it is forwarded by contrarotating conveyers S to a sewing station C, suction pad separators 40 are operated to remove a card from the front of a stack B1 and deposit it at the entrance of contra-rotating conveyers 12, 14 which forward the card B into register with the bag 18 prior to sewing. The cards B1 in the stack are stood on edge on an incline. A weighted pusher 34 inches the stack forwards as the front card is removed by the separator. Air blast from a perforated tube 42 assists in the separation of the front card. The suction separators 40 are mounted on approximately mutually perpendicular telescopic levers 72, 76 pivoted respectively at 74 and 78. A pair of cams 54 and 56 co-operate with follower rollers to cause the separators to advance first towards the stack to pick up a card, and then towards the contra-rotating conveyers 12, 14. Together with cams 54 and 56 on shaft 44 is a further pair of cams (46 and 50, Fig. 5) for controlling the pneumatic circuits of the separators 40 and the air blast tube 42. A fifth cam (30) controls an electric switch (28) which shuts down the separator mechanism at the end of a cycle. The cycle is initiated, as stated above, by switch 20 detecting the leading edge of a bag. The switch 20 energizes a clutch (26, Fig. 4) in the drive to shaft 44.
