Ear bonding device for use in packaging machines

摘要

An ear bonding device for use in packaging machines comprises a container transport conveyor having a plurality of holders for holding a container having upper and lower ears as supported on each pair of adjacent holders, the conveyor being intermittently drivable so as to halt containers held by the holders one after another at a pressure-bonding station; an upper ear pressing member disposed above a path of transport of containers at the pressure-bonding station and movable upward and downward; a pair of lower ear pressing members arranged at opposite sides of the transport path respectively and movable toward and away from each other; and a support member for receiving the pressure of the upper ear pressing member and the lower ear pressing members acting on the holder for pressure bonding.
