A draw frame of a sliver-drafting apparatus has three cascaded roller pairs whose lower rollers are driven by respective motors at speeds determined by associated frequency dividers and/or multipliers in the output of a common oscillator of adjustable operating frequency. The slivers drafted by the roller pairs form, after doubling or plying, a fiber bundle traversing a thickness sensor whose output, integrated over predetermined time periods, is used by a microcomputer to ascertain optimum nip-line spacings and contact pressures reducing the thickness variations to a minimum. These parameters can be varied by horizontal slides supporting the roller pairs and spring-loaded blocks acting upon the shafts of the upper rollers; the positions of the slides and the pressures of the loading springs are adjustable by servomotors, under the control of the microcomputer, on the basis of a running-in program in which different combinations of values for the spacings and the pressures are successively set up and the combinations yielding the highest degree of uniformity are subsequently re-established.

Method of controlling fiber-drawing apparatus

Means for controlling fiber-drawing apparatus

There is provided herein an automatic can changing device for spinning preparation machines such as for drawing frames, carding or combing machines in which a stationary conveyor is provided that is associated with a fiber lap delivery station, with mechanism for removing empty cans from the conveyor and presenting them to the fiber lap delivery station for the filling operation and thereafter removing these filled cans from the fiber lap delivery station and depositing them in an intermediate station preparatory for introduction to movable carriages also being shown.

Can changing device

A mechanism for rotating a cannister during the filling of the cannister with textile material from a carding machine or the like which includes a turntable rotatably mounted on a frame for supporting a cannister having a movable bottom including a plurality of flexible metal bands arranged on the frame for reciprocating movement between a retracted and an extended position with upper end portions in angularly disposed relationship, the upper ends of the bands secured together for underlying engagement with the cannister bottom and the adjacent side edges of the bands provided with releasable interlocking means engageable during the movement of the upper portions of the bands into the extended position to form a pillar together with drive means for moving the bands between the retracted and extended positions to permit downward movement of the cannister bottom during the filling of the cannister with textile material.

Cannister rotation mechanism

A mechanism for rotating a cannister during the filling of the cannister with textile material from a carding machine or the like which includes a turntable mounted on a rotatably driven housing, the turntable being arranged to support a cannister having a movable bottom, a spiral spring having a lower end positioned in the housing with a support member on its upper end in underlying engagement with the cannister bottom for urging the bottom into an upper position together with a power driven winch disposed in the housing having a cable connected to the support member for lowering the cannister bottom downwardly against the force of the spring during the cannister filling operation.

Disclosed is a cannister rotation mechanism for use in combination with a fiber carding or drawing frame having a turntable arranged to deliver fiber into the cannister. Reciprocable means are shown for raising and lowering the movable cannister bottom into position to receive the fiber and later to remove the filled cannister and insert a new cannister for filling. Several embodiments of the reciprocable means are shown and described.
