ABSTRACT:
A spinning machine arrangement is provided having fiber feeding and opening apparatus arranged upstream of the spinning turbine with respect to a supply of fibers to be spun. This apparatus includes a feeder roll and an opening roll arranged serially in the travel path of the fiber stream, said rolls being housed in a housing having one side formed by a flat baseplate. Individual separate guide parts are detachably attached to this baseplate for guiding the flow of fibers and air through the feeder roll and opening roll. These guide parts are constructed of different materials and machined to different tolerances in dependence upon the specific loads and requirements experienced in use due to the configuration and operation of the apparatus. A cover plate is disposed parallel to and in facing relationship to the baseplate, with the opening and feeder rolls, as well as at least a portion of the guide parts disposed therebetween. In preferred embodiments, the axle for the opening roll also operates as a pivot axis for the baseplate, with the opening roll being bearingly supported in the base plate. In this manner, pivotal movements of the baseplate effect engagement and disengagement of the opening roll with driving means thereof. At least some of the guide parts are attached to the baseplate to be adjustable in the radial direction with respect to the opening roll axis, so as to accommodate variable exact positioning thereof.
