Abstract
A bag closing apparatus is provided having a frame, a closure strip guide, a clip separator, and a bag feed conveyor. The frame is configured to carry a strip of closures. The closure strip guide is configured to guide a strip of closures. The clip separator is configured to sever a terminal closure on a strip of closures exiting the strip guide. The bag feed conveyor has a pair of laterally spaced-apart drive wheels and a complementary pair of laterally spaced-apart follower wheels urged into engagement for coaction with the drive wheels to deliver a bag neck into the terminal closure. The drive wheels and the follower wheels each comprise a circumferential outer periphery having a friction-reducing surface having a static dry coefficient of friction of at most 0.2. A method is also provided.
