Improvements to splicer devices for the mechanical splicing of textile yarns, and mechanical splicer device which employs such improvements.

摘要

This invention is obtained with improvements to splicer devices (10) making a splice between two yarns by the mechanical removal and recomposition of twists, such splicer devices (10) comprising means to untwist and retwist yarn which have a substantially circular form, such means possibly including operational means (70).
<??>Such splicer devices (10) include means able to pluck and/or tear excessive tail ends of yarn and to obtain small remaining tails of yarn.
<??>According to the improvements of the invention such splicer devices (10) contain at least one of the following aspects:
adjustable cam means (37-38) which condition the untwisting and retwisting separately,
spacer means (91) able to keep the surfaces which work on the yarn, at a desired distance at least momentarily,
movable portions (47-147) of the plucking and/or tearing means (42-142) which can move in opposite directions, and
means to tension yarn (101) which carry out a drawing action,
the surfaces on which the operational means (70) are placed being conformed as required.
<??>The invention is also embodied with splicer devices (10) which employ the above improvements.
