    Abstract: In the case of a drafting unit for a spinning machine, a loading support is provided which has two arms extending in parallel with respect to one another at a distance which accommodate the holding devices for the shafts of the pressure roller twins and which are reinforced to form a frame by means of cross-struts. In addition, a cover is provided which covers the loading support and the pressure rollers and which can be swiveled away without interrupting the spinning operation.

    Abstract: An apparatus on a drafting system of a spinning machine, especially a draw frame, carding machine, combing machine or the like, for weighting the drafting system rollers, has at least one pressure fluid cylinder with a piston which is acted upon by pressure fluid and is arranged so as to be axially movable inside a cylinder housing and from which a piston rod extends. The piston rod passes through at least one cylinder cover that forms the end boundary of the cylinder housing. For determining the position of the piston with the piston rod, an optical distance sensor scans the distances with respect to a counter-element and the distance sensor is connected to an evaluation device.

    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.
