A new automatic feeder for collar plasticizing machines, includes a loader, subdivided into a plurality of compartments where the collars are piled, a movable frame capable of alternating rectilinear motion along side slides and supporting pneumatic cylinders which are provided at the lower end with bellows suckers for sucking in the collars onto the conveyor belt into the plasticizing machine. An electromagnet imparts an alternating oscillatory motion to lamellar members which act as locking members for the tubular members and causes the lamellar members to release the tubular members so that the tubular members and the bellows suckers drop by gravity. After the collars have been sucked in, the tubular members have reached their upper position, and in a subsequent stage, the lamellar members return to their locking position, because the electromagnet is no longer energized. |
