Abstract:
A draw frame comprising(a) a transport roll pair for simultaneously guiding a plurality of slivers running in an advancing direction; (b) a series of drafting roll pairs spaced from one another in said advancing direction; one of said drafting roll pairs being a first drafting roll pair as viewed in said advancing direction; said first drafting roll pair being positioned downstream of said transport roll pair; and (c) a measuring device contacting the running slivers; said measuring device including (1) a pressure-sensitive member exposed to a force derived from the running slivers for emitting a signal representing said force; and (2) deflecting means for deflecting the running slivers for causing the running slivers to be partially trained about said deflecting means to exert on said pressure-sensitive member a pressing force proportional to a tension of the slivers prevailing upstream and downstream of said pressure-sensitive member.
