## 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.

## Claims

### Claim 1

A method of severing and spacing a first web of material comprising:
providing a first web of material at a first speed;
severing said first web to create a first and a second portion of said first web;
providing said first and second portions of said first web to an accelerating unit;
creating a first gap space between said first and second portions of said first web;
severing said first and second portions of said first web to create a first and a second subdivision of said first portion of said first web; and a first and a second subdivision of said second portion of said first web;
providing said first and second subdivisions of said first portion of said first web and said first and second subdivisions of said second portion of said first web to an accelerating unit to create a second gap space in a machine direction between said first and second subdivisions of said first portion of said first web and a second gap space between said first and second subdivisions of said second portion of said first web; and
coupling said first and second subdivisions of said first portion of said first web and said first and second subdivisions of said second portion to a carrier web,
said method further comprising providing a left lane and a right lane of aid first web of material,
said method further comprising coupling said second subdivision of said first portion of said left lane of said first web, and said first subdivision of said first portion of said right lane of said first web to a first carrier web; and coupling said first subdivision of said first portion of said left lane of said first web, and said second subdivision of said first portion of said right lane of said first web to a second carrier web.

### Claim 2 (depends on 1)

A method according to claim 1, said method further comprising coupling said second subdivision of said second portion of said left lane of said first web, and said first subdivision of said second portion of said right lane of said first web to said first carrier web; and coupling said first subdivision of said second portion of said left lane of said first web, and said second subdivision of said second portion of said right lane of said first web to said second carrier web.

### Claim 3 (depends on 2)

A method according to claim 2, said coupling step comprising ultrasonic bonding.

### Claim 4 (depends on 1)

A method according to claim 1, the method further comprising passing said first and second webs carrying said portions of said first and second webs to an apparatus for severing said first and second webs and reorienting selected severed portions of said first and second webs.

### Claim 5 (depends on 4)

A method according to claim 4, the method further comprising tack bonding said subdivisions to said carrier webs.

### Claim 6 (depends on 1)

A method according to claim 1, the method further comprising folding said subdivisions over said carrier webs.
