摘要

Apparatus for assisting the return of threads into respective dwell and presentation channels within warpers carrying out thread-by-thread warping and provided with a thread-holding hook (2) intended for picking up and winding individual threads onto a support offered by the warper according to a sequence corresponding to the selected warping program, comprising a plurality of flat elements (1) cascade-like disposed unidirectionally in the direction (D) of transit of the threads each time engaged by the thread-holder (2) within an area (H) between the warper and a reel for the support of the threads, each of said elements (1) exhibiting a portion (11) which engages the corresponding thread being in a dwell and presentation attitude and movable between a position in which said portion (11) engages the corresponding thread and a position in which the thread is disengageable from said portion (11) by means of the thread-holding hook (2) which transits within said area (H).
