## Abstract

A winding method includes rotating a winding drum; transferring a first web structure from a first lay down station to the web stabilizing bed of a first winding station; cutting the web structure; contacting the web structure with a web assembly hold down element, winding the web structure into a roll assembly; and discharging the roll assembly from the winding drum.

## Claims

### Claim 1

A method of winding a layered structure comprising steps of:
a) rotating a winding drum, the winding drum having a circumference;
b) transferring a first web structure from a first lay down station to a first winding station of the winding drum;
c) contacting the web structure with a winding mandrel;
d) contacting the web structure with a web assembly hold down element, wherein the web assembly hold down element is disposed adjacent to and extends along a portion of the circumference of the winding drum;
e) winding the web structure by rotating the winding mandrel;
f) fixing a trailing edge of the web structure relative to the wound structure;
g) discharging the wound structure from the winding drum, wherein the first lay down station and the web assembly hold down element are provided by different structure.

### Claim 2 (depends on 1)

The method according to claim 1 further comprising the step of separating a portion of the web structure from the remainder of the web structure.

### Claim 3 (depends on 1)

The method according to claim 1 further comprising the step of concurrently winding a plurality of web structures.

### Claim 4 (depends on 1)

The method according to claim 1 further comprising the step of attaching the first web to a second web prior to winding the web structure.

### Claim 5 (depends on 1)

The method according to claim 1 further comprising the step of overwrapping the wound structure.

### Claim 6 (depends on 1)

The method according to claim 1 further comprising the step of laying the web structure down into a web track.

### Claim 7 (depends on 1)

The method according to claim 1 further comprising the step of laying down a second web structure in a face to face relationship with the first web structure.
