Abstract
An apparatus and method for separating a multi-strand elastic feed (1) comprising: an apparatus for separating a multi-strand elastic feed (1) comprising: a feed roll (2); a series of pins (3) for separating the feed located downstream from the feed roll said series extending laterally to the machine direction (9), the series comprising a first feed pin (4) and a subsequent set of separator pins (5); and wherein the spacing of the pins in the series is such that the separation of adjacent pins in the cross direction is less than the diameter of a separator pin, wherein in use, the multi-strand elastic feed is threaded manually around the feed pin and is then separated such that the strands pass around the separator pins in a direction opposite to that traveled round the feed pin with the result that the multi-strand elastic feed is separated into strands separated in the cross direction and a tensioning means to facilitate the initial threading of the feed around the pins; and a means for passing the separated strands directly for further processing (8) for incorporation into a laminate.
