A stop motion apparatus for a drafting device for roving in a textile machine includes a stop member into roving stopping engagement with the intake feed rollers of the drafting device by operation of an actuating rod. The actuating rod includes a notch having an undercut surface for engagement by a plunger element. Preferably, the undercut surface is transversely arcuate and the plunger element includes a plastic sleeve element compatibly configured with the actuating rod notch. the plunger element is selectively insertable into, and retractable from, the notch of the operating rod by an electromagentic assembly operatively connected to a yarn break monitor. The stop motion apparatus includes a shaft having a forked end for manually clearing the plunger element from the actuating rod notch.

Stop motion apparatus for a roving drafting device of a textile machine

An apparatus for supporting a stop member of a stop motion device of a textile ring spinning machine is provided. The apparatus includes a carriage having a cam portion for removably receiving and manipulating the projecting cam follower portion of the stop member, a device for reciprocating the carriage and a device for releasably positioning the carriage on the reciprocating device in a predetermined position. The carriage is disengagable from the positioning device for movement therefrom sufficiently to permit removal and replacement of the stop member from the carriage and is reengagable with the positioning device for positioning the carriage in its predetermined position. Preferably, the carriage and the positioning device each includes cooperatively configured portions for releasable interengagement with one another to position the carriage in its predetermined position.

Apparatus for supporting a stop member of a textile ring spinning machine

An improvement in a roving stop motion for a spinning machine of the type having a series of pairs of drafting rollers, the stop motion including a clamping member mounted on a lever arm drivenly connected to an actuating rod by a carriage which is selectively mountable at differing locations along the actuating rod. The actuating rod is responsive to roving breakage to drive the lever arm to cause the clamping member to separate the feed rollers from one another and press the roving against one roller. The positionability of the carriage enables the lever arm to be properly disposed with respect to the feed rollers when the spacing between the roller pairs is varied.

Roving stop motion for a spinning machine drafting system

Apparatus for guiding the travel of roving between succeeding roller pairs at a spinning machine drafting station having telescoping tube members defining a roving guide channel therethrough and displaceable apart from one another to be variable in length for adjustable disposition between the nip areas of the successive roller pairs throughout a full range of different spacings therebetween.

Roving guide apparatus

Along the ring bank of a twisting or spinning machine is provided a shaft rotatable about an axis parallel to the ring bank and supporting holders for thread-break sensors inductively responding to the orbiting of the travelers. Since the holders are independent of the ring bank, they can be swung out of the way to allow replacement or maintenance of the ring bank.

Thread-break monitor for ring-spinning and ring-twisting machines

A drafting assembly whose lower belt is laterally guided by a guide element having a pair of side walls joined by a web and more unitarily from a synthetic resin. The web lies outside the loop of the lower belt and in the upper belt or adjacent the lower belt. The element is held against lateral movements by abutments which can be lateral flanks of the rollers or a guide element for the upper belt. The element is prevented from twisting or rotation by engagement with a stationary turnover rail over which the lower belt passes.

Drafting assembly for a spinning machine

In order to make possible automatic restart of a spinning machine drafting frame after strand breakage in an easy way, a movable blocking member is insertable between the drive roller of the lower feed belt and the lower feed belt in the direction of the line of contact of the lower feed belt and the drive roller, this blocking member on engagement raising the lower belt from its drive roller by operation of a connecting rod attached pivotally to the detent member. Additional roller pairs present upstream of the feed belts are preferably provided with means for simultaneously lifting the various upper rollers from the lower rollers with or without holding the yarn or thread fixed on engagement of the detent member.

Spinning machine drafting frame

Spinning machine in which the upper rollers of the drafting units are arranged at pressure arm assemblies, whereby each pressure arm assembly has a main arm and an operating lever which is positionally arranged above the main arm and radially movable. To each work location of the machine are assigned signal lights for indicating disruptions at the work location. For optimum visibility from distant locations, the indicator lights are provided at the operating levers.
