Abstract
A seam bonding system includes a drum rotatable about an axis. A seam bonder is mounted to the drum such that the seam bonder is rotatable with the drum about the axis. A horn of the seam bonder is movable along a transverse direction over an anvil of the seam bonder. The seam bonding system also includes features for positioning a lobe of a web material on the drum while the horn of the seam bonder moves along the transverse direction over the anvil of the seam bonder.
Claims16
A seam bonding system, comprising:
- a drum rotatable about an axis;
- a seam bonder mounted to the drum such that the seam bonder is rotatable with the drum about the axis, a horn of the seam bonder movable along a transverse direction over an anvil of the seam bonder;
- and
- a lobe positioner mounted to the seam bonder such that the lobe positioner is movable along the transverse direction with the horn of the seam bonder, the lobe positioner comprising a pair of slides positioned opposite each other about the anvil of the seam bonder, the pair of slides configured for engaging and positioning a lobe of a web material on the drum when the horn of the seam bonder moves along the transverse direction over the anvil of the seam bonder.

1 more element
A method for seam bonding, comprising:
- rotating a drum with a web disposed on an outer surface of the drum;
- moving a horn of a seam bonder along a transverse direction over an anvil of the seam bonder;
- while the horn of the seam bonder moves along the transverse direction over the anvil of the seam bonder, engaging a lobe on the web in order to stretch elastic bands within the lobe;
- and
- while the elastic bands within the lobe are stretched, forming a seam bond with the seam bonder.
