Abstract
Abstract A machine for assembling plastic bags on wickets as a step in the production of packets of plastic bags. A plastic bag having a flap provided with mounting holes is fed vertically downward between the suction transfer arms of a rotating double set of transfer arms which carry the bag to wickets mounted in register with the flap holes. By feeding the bags vertically downward between the suction transfer arms the problems of transfer caused by static charges and glossy surface are minimized.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
170 words
A bag packet assembling machine adapted to assemble bags on wickets, said wickets having at least two wicket posts, comprising: 1. means for providing a plastic bag having a flap pierced by at least two holes, 2. movable suction transfer arms provided with openings on their leading sides adapted to hold a plastic bag by suction, said arms being adapted to sweep through the area located directly beneath the output position of the bag-providing means, 3. means for connecting the openings of the suction transfer arms to a source of suction, 4. means for delivering the plastic bag vertically downward free from guiding means into the sweep area of the transfer arms so that the bag becomes affixed thereto by suction, and 5. wicket support means located adjacent to the transfer arms and adapted to maintain the posts of the wicket in register with the holes of the flap of the bag carried by the transfer arms, so that the bag is transferred from the transfer arms to the wicket.
