    摘要： A device for the transverse welding of plastic webs to produce bags and the like has a welding beam with a rounded edge turned toward the web juxtaposed with a welding roller which can have a plurality of rings mounted thereon to advance the weld seam length or transverse the welding width the rings can be coated with polytetrafluoroethylene and adjustment of the device to greater or reduced welding widths is accomplished by adding or subtracting the rings which are contiguous with one another.

    摘要： A cross sealer for a plastic bag making machine includes a frame with an upper moveable seal bar unit and an opposed lower stationary seal bar unit. The movable unit is a lightweight construction seal beam. A rotating shaft spans the cross sealer and is connected by a plurality of eccentric linkages to the seal beam. The linkages moves a seal bar into sealing engagement across the width of the web to the seal bar unit constructed with a support beam and a seal bar connected to the beam. The seal bar unit is mounted as a substantially stationary unit during sealing and is supported by a plurality of air cylinder units for positioning from standby to an operating position. Each air cylinder unit includes an adjustable stop unit secured to the back of the cylinder unit and connected to the cylinder piston for adjusting the movement of the piston and thereby the operative sealing position of the stationary seal bar unit. Some air cylinder units are connected to the seal bar unit for positively moving the same and others additionally includes pad abutting the seal bar units for supporting the same between the two positions.

    摘要： An apparatus (31) and a method are disclosed for performing an operation upon multiple webs (51,53), including the feeding of multiple webs (51,53), the provision of a carrier (65) for assisting in moving the webs (51,53) along a predetermined path (83), the performance of an operation (69) upon the webs, the insertion of a carrier (65) between the webs (51,53), and the provision of a sealing device (71) for sealing the webs together to form a sealed portion (75) to cooperate with the carrier (65) for assisting in moving the webs (51,53). The carriers (65) are mounted on a conveyor (83) and each carrier (65) pushes against the sealed portion (75) to pull the webs (51,53), and the packages (41) formed therefrom in the direction of conveyor travel. The preferred carrier (65) has a shaped head on the end of a flat plastic blade. The shaped head may have an opening (81) therein of a smaller size than the sealer (188) inserted into the opening such that the fused plastic may extrude outwardly to abut the edge (79) of the carrier defining the opening.
