    摘要： Device to automatically cut the slubbing, or spinning sliver, (11) of a yarn being worked, the device being used in any textile machine whatsoever and comprising a cutting assembly and sensor means (18) functionally associated with the cutting assembly, the sensor means (18) being suitable to detect the presence or absence of the yarn (11a) downstream of the draft and to activate the cutting assembly at least when they do not detect the presence of the yarn (11a), the cutting assembly comprising a support with which a blade is associated, the blade being movable with respect to the support to selectively assume an inactive position of non-interference with the slubbing (11) passing through or a cutting position in which it abuts against a contrasting element to cut the stubbing (11) transversely, the cutting assembly (17) comprising an electromagnet (21) and a magnetic element (35) suitable to cooperate with the movable blade (26) to keep it constrained to the core (21a) of the electromagnet (21) to assume the inactive position (26a), the electromagnet (21) being able to be temporally activated to generate a magnetic field suitable to take the blade (26) to the cutting position (26b), against the action of the magnetic element (35).

    摘要： A stop motion device for a textile strand processing machine including a sensor positioned between a supply package and a take-up package for sensing the presence or absence of a strand within a defined sensing range of the sensor and a strand breaker positioned between the supply package and the sensor. The strand breaker includes a pivot for pivotally mounting the strand breaker for movement between an inoperative position in disengagement with the strand and a strand breaking position in engagement with the strand. The pivot is positioned with relation to the path of movement of the strand for pivotal movement of the strand breaker in the direction of movement of the strand and towards and into the path of movement of the strand for breaking the strand upstream of the take-up package. A release cooperates with the sensor and the strand breaker for releasing the strand breaker when the sensor senses the absence of a strand within its sensing range.

    摘要： A textile machine such as a spinning machine has, for each spindle, a comparator which senses the voltage at a motor driving said spindle and compares it with a reference voltage. Upon the comparator sensing such a change in the motor voltage as would be consistent with breakage of the material being worked on the machine (e.g. a roving passing towards the spindle and being spun into a thread), it operates a switch which serves both to switch off the motor driving the spindle and to arrest the material passing to the spindle.
