Abstract
A web splice for attaching two webs, such as paper webs used in paper converting operations. The web splice comprises a non-linear butt joint. The butt joint forms an acute included angle (α) with the side edges.
Claims10
A web splice for attaching two webs, the web splice comprising:
- a first, expiring web having a trailing edge and first side edges defining a first width (W1), the trailing edge defining a first shape that is non-linear, the first side edges being parallel to a web running direction (D);
- a second, trailing web having a leading edge and second parallel side edges and a second width (W2) the same as the first width (W1), the leading edge defining a second shape that is non-linear, the second side edges being parallel to the web running direction (D);
- the trailing edge and the leading edge forming a non-linear butt joint;
- and
- an adhesive member adhered to the first web and the second web and overlapping at least a portion of the butt joint;
- wherein
- the butt joint comprises a middle section, two side sections and an apex, the middle section located downstream of the two side sections, each side section terminating at a junction of a first side edge and a second side edge, each side section forming an acute included angle (α) with a first side edge of the first web.
