Abstract:
The present invention provides a method of providing a disposable product with zero waste ear formation and attaching the ears to a running chassis web. A cut/slip operation is performed on an incoming web carried by a transfer drum, and the cut/slip pieces are further divided and next separated by a second transfer drum and bonded to incoming webs.
Abstract:
A web unwinding and splicing system includes a turret unwind having a turret arm with rotatable shafts at opposing ends thereof to unwind a running web of an expiring web material roll and unwind a waiting web of a new web material roll. A web splicing unit operable with the turret unwind includes a web deflection device that bumps the running web onto the waiting web to splice the running web with the waiting web and a cutting device that selectively severs the running web, thereby creating a leading portion of the running web that is spliced to the waiting web and a trailing portion of the running web that remains separate from the waiting web. A vacuum system is positioned proximate the running web to suction in the trailing portion of the running web left on the expiring web material roll.
Abstract:
The present invention provides machinery used to create products (for instance disposable products). The machinery is operated at high speed, with the machine occupying a small footprint. Materials can be fed into the manufacturing process vertically (from above or below), using assembly stations to feed completed components into the system at appropriate stations. Additionally, restocking of raw components can be accomplished by robotic means of transferring the raw material from staging areas into infeeding or splicing stations, without the need for human operators.
Abstract:
A variable interference anvil and knife combination is provided to selectively sever elastics in a laminate and preferably not sever the nonwoven portions of the laminate. The distance between the anvil and the knife can be programmatically altered to provide for smaller or larger gaps as processing speeds are changed.
Abstract:
Ventilated vacuum structures such as pucks and rings are disclosed for carrying portions of disposable products during manufacturing. Air flow enters vacuum commutation ports on an article carrying structure from vents nearby, the vents receiving air from a side, a top or an underside of the article carrying structure.
