Abstract
A method of assisting in the seaming of a papermaker's fabric using a seam assist device is disclosed. The seam assist device is comprised of two portions. Each portion having an attaching edge that is attached to a predetermined distance from the ends of the fabric by fitting spiral or loop elements into voids in the surface of the fabric and anchoring the elements using a binder or pintle. Connecting edges on each portion are then connected together, thereby causing the two attached ends of the fabric to be brought together for seaming.
Claims21
A seam assist device for assisting in the seaming of a papermaker's fabric, comprising:
- a first portion having a first attaching edge for attaching to the fabric in the cross-machine direction and a first distance in the machine direction from a first end of the fabric, and a first connecting edge;
- the first attaching edge having spiral or loop elements integral therewith or attached to loops formed thereon which are fitted into voids in or are otherwise attached to the surface of the fabric and anchored using a pin yam or pintle;
- a second portion having a second attaching edge for attaching to the fabric in the cross-machine direction and a second distance in the machine direction from a second end of the fabric, and a second connecting edge;
- the second attaching edge having spiral or loop elements integral therewith or attached to loops formed thereon which are fitted into voids in or are otherwise attached to the surface of the fabric and anchored using a pin yam or pintle;
- and
- said first connecting edge being connectable to the second connecting edge, whereby the first and second ends of the fabric are brought together for seaming by the attached first and second portions when the first and second connecting edges are connected.
A method of assisting in the seaming of a papermaker's fabric using a seam assist device, comprising the steps of:
- a first attaching step of attaching to the fabric a first attaching edge of a first portion of the seam assist device in the cross-machine direction and a first distance in the machine direction from a first end of the fabric;
- the first attaching edge being attached by fitting spiral or loop elements integral therewith or attached to loops formed thereon into voids in or are otherwise attached to the surface of the fabric and anchoring the elements using a pin yarn or pintle;
- a second attaching step of attaching to the fabric a second attaching edge of a second portion of the seam assist device in the cross-machine direction and a second distance in the machine direction from a second end of the fabric;
- the second attaching edge being attached by fitting spiral or loop elements integral therewith or attached to loops formed thereon into voids in or are otherwise attached to the surface of the fabric and anchoring the elements using a pin yarn or pintle;
- and
- a connecting step of connecting a first connecting edge of the first portion of the seam assist device to a second connecting edge of the second portion of the seam assist device, whereby the first and second ends of the fabric are brought together for seaming.
