Abstract
High speed, continuous processing of product pieces with desirably extended durations of application of bonding or bonding energy.
Claims24
A high speed process for bonding a series of pieces each to itself comprising:
- supplying a series of pieces to be bonded,
- splitting the series of pieces to be bonded into first and second subseries of pieces to be bonded,
- bonding the first subseries of pieces to be bonded to form a first series of bonded pieces, and
- bonding the second subseries of pieces to be bonded to form a second series of bonded pieces.

A continuous high speed process for ultrasonic bonding a series of pieces each to itself comprising:
- supplying a series of pieces to be bonded,
- splitting the series of pieces to be bonded altematingly into first and second subseries of pieces to be bonded,
- folding members of the first subseries of pieces to be bonded into bonding relative position,
- folding members of the second subseries of pieces to be bonded into bonding relative position,
- ultrasonically bonding the first subseries of pieces to be bonded to form a first series of bonded pieces, and
- ultrasonically bonding the second subseries of pieces to be bonded to form a second series of bonded pieces.

A process for side seam bonding of a disposable pant-like garment for absorbing human discharge comprising
- supplying a series of planar garment precursor pieces to be bonded,
- splitting the series of pieces to be bonded alternatingly into first and second subseries of pieces to be bonded,
- folding members of the first and second subseries of pieces to be bonded into bonding relative position,
- sequentially ultrasonically bonding the folded members of the first subseries of pieces to be bonded to form a first series of bonded pieces, and
- sequentially ultrasonically bonding the folded members of the second subseries of pieces to be bonded to form a second series of bonded pieces,
- wherein a folded member of the first subseries of pieces to be bonded and a folded member of the second subseries of pieces to be bonded are bonded substantially simultaneously.
