Estimating the term…
A drawing frame for a spinning machine is provided with a blocking mechanism movable into a position between the upper and the lower feed rollers in the event of yarn breakage, to lift the roving from contact with the driven roller. A roving holder facilitating the holding of the tuft end of the roving between the drawing and outlet rollers is provided. This latter apparatus is coupled to the means for actuating the blocking mechanism for synchronous operation and is provided downstream of the inlet roller. It comprises a table extending beneath the roving and a rotatable shaped arm above the roving which arm is movable by the switching mechanism to simultaneously hold the front end of the roving.
A draw frame for a spinning machine converting a roving into a thread having upper and lower paired inlet and outlet rollers and an upper and lower paired drafting rollers therebetween, means for sensing a break in said thread, a blocking device for arresting the motion of said roving, and a holding device for securing the forward end of said roving in alignment with said drafting rollers, switch means operable in response to said sensing means for operating said blocking and holding devices, said holding device being adjustably mounted between said paired inlet rollers and said drafting rollers along the path of movement of said roving.
The draw frame according to claim 17 wherein said wedge is movable with respect to said supporting rail at right angles to plane of said roving and is biased by a spring to lie below the side of said roving pointing to the lower roll.
