Apparatus for splicing a replacement web to a moving web.

摘要

Apparatus for splicing a replacement web (r2) to a moving web (r1) comprising a guide (G) for guiding the moving web (r1) along a predetermined path (a1). A cutter (10'') severs a portion of the replacement web (r2) to establish the leading edge thereof; and a splicing station (H) is positioned in the path (a1) of movement of the moving web (r1) for splicing the leading edge of the replacement web (r2) to the moving web (r1) while the latter is moving. The replacement web (r2) is fed from a reel (R2). Before the said leading edge is cut a leader (P) which is stuck by adhesive thereon to the remainder of the rods (r2) is removed by a nipping device (6') which grips said leader (P) and whilst it is so held the reel feeds out web (r2) so that a loop is formed. The leader (P) is stuck by the adhesive on the leader (P) to the other side of the loop so that a closed loop is formed. A rod (40) is engaged in the closed loop and serves to feed the web (52) to an auxiliary feed means (F') which in turn feds it to the cutter (10').
