ABSTRACT:
A selvedge-forming mechanism for forming a recessed selvedge in a fabri produced by a shuttleless loom includes elements for gripping and cutting the pick inserted into the shed, a needle which captures the tail of the cut pick and causes the tail to enter again, in a bent-back, i.e., doubled-back condition, in the shed. The shed closes onto the bent-back, cut pick, thereby providing the recessed selvedge. The mechanism also includes a respective kinematic drive for performing the gripping and cutting, and for the needle. The drive kinematic drive includes a first side carriage and a second side carriage, these side carriages being disposed opposite to each other and having the gripping elements and cutting elements installed on them, and a third, central carriage on which the needle is installed. The three carriages are driven to reciprocate by respective cams, which directly act on them, with only the interposition of respective cam followers.
