Abstract: In an apparatus on a drafting system of a spinning room machine, especially a draw frame, carding machine, combing machine or the like, for weighting the drafting system rollers, at least one pressure-medium cylinder with a piston is acted upon by pressure medium and is arranged so as to be axially movable inside a cylinder housing. A piston rod extends from piston passing through at least one cylinder cover that defines the cylinder housing at the end. In order to improve the apparatus, for determining the position of the piston with the piston rod, at least one inductive displacement sensor is integrated into the pressure-medium system, and the inductive displacement sensor is connected to an evaluation device.

Abstract: An apparatus on a draw frame for textile fiber slivers has a drawing system having weighting of the top rollers of successively arranged pairs of rollers comprising a bottom and a top roller. During operation, the top rollers are pressed against the bottom rollers by weighted pressure elements in pressure arms. Two pressure elements with a common holding element are associated with each top roller and the weighting device is removable. To improve the said apparatus, a pressure element is rotatably or pivotally mounted at a center of rotation or a pivot bearing and the pressure elements are connected with one another by a supporting element.

Abstract: A guide arm of a top roll loading system of a drafting unit is pivotally mounted on a bracket, with the pivot thereof positioned a substantial distance below and rearwardly of the plane of all of the drafting rolls so that yieldable force applied to the guide arm is transmitted to the top rolls in an inclined downward and forward direction, as is particularly desirable where the back or feed top roll is offset rearwardly of the back or feed bottom roll of the drafting unit. Also, a novel compound linkage connects a yieldable force means to a latch arm pivoted on the guide arm and is so designed that a compression spring or a pressurized pneumatic bag or tube may be used alternatively as the yieldable force means therefor by a simple interchange of parts.

Abstract: A spinning machine for the doubling or stretching of fiber bands with a rolling section having lower rolls which are secured in journal blocks, and wherein the upper rolls may be also secured on said journal blocks with pressure means for the loading of said upper rolls, it is proposed that the pivoting axis of the pressure arm for the placement of the pressure means to the upper rolls be arranged in such a way that, when observed in the running direction of the fiber band, said axis lies behind the rolling section. Advantageously, what is achieved thereby, is that the spinning machine can be maintained in a considerably simpler and quicker manner. Following the upward pivoting of the pressure arm, the entire area of the rolling section becomes freely accessible. The pivoting geometry of the pressure arm can be so varied, that the upper rolls can be easily restored into the guides on the journal blocks of the lower rolls.

Abstract: An automated drafting system particularly suitable for drafting textile strands of sliver is provided. The automated drafting system includes a synchronous drive sliver drafting roller system utilizing toothed gears in the preferred embodiment operatively connecting a pair of drafting rollers with one of the rollers being directly driven by a motor to thereby cause identical rotation of both rollers. The automated drafting system also includes a system for securing and pressuring together upper and lower sliver drafting rollers wherein the lower roller of a pair of drafting rollers is preferably maintained in a fixed but rotational position while the upper roller of the pair is pressured towards the lower roller and controllably restricted as to both horizontal and vertical movement during the drafting process. A sliver autoleveling system using tongue and groove drafting rollers to sense sliver uniformity is also included in the automated drafting system utilizing linear variable differential transformers (LVDTs) to monitor vertical displacement of the upper roller of a roller pair relative to the lower roller. The automated drafting system further provides a feed-forward and feed-back autoleveling system for control of sliver drafting rollers utilizing an input sliver sensor and an output sliver sensor communicating with a computer to facilitate sliver uniformity. A draftless sliver coiler packaging system is still further provided by the automated drafting system and utilizes a sliver level sensor to controllably and automatically adjust the speed at which sliver is packaged subsequent to emergence from a variable speed sliver delivery system.
