Abstract: Starting on the surface of a foundation body (2) weld material is applied in runs to form layers by an equipment for profiling building-up welding and hence a workpiece (1) is manufactured, where the foundation body (2) may be a component of the workpiece (1). The course of runs to form layers as well as the approximate rate of application of weld material are calculated by a computer system (11), starting from a two- or three-dimensional data model of the workpiece (1) in the form of software, and given over to the system control (10) which positions the welding torch (7) by means of the robot (5) and the workpiece (1) located on a turntable (4) by a clamping mechanism (3) with respect to one another, and regulates the rate of application of weld material applied by the welding apparatus (8) in such a way that the liquid weld material adheres to the layer lying underneath without running down and irregularities in the runs to form layers are levelled out.

Abstract: The present invention concerns a method of automatically doffing the full bobbin packages from, and donning the empty bobbin tubes onto, the spindles of a preparatory spinning machine equipped with flyers. The flyers are of the so-called suspended type, i.e. they are rotatably supported in a flyer head.For the conjoint, vertical doffing of the full bobbin packages, and for the conjoint, vertical donning of the empty bobbin tubes the flyers are pivoted to the side in such manner, that they cannot obstruct the doffing of the full bobbins any more.The inventive preparatory spinning machine comprises a common support beam in which the flyers are rotatably supported, in which arrangement the beam can effect a translatory movement in such manner that each flyer can be brought into an inclined position.

Abstract: The present invention concerns a flyer for roving frames. According to the invention the flyer arms (14,16) at their free ends are connected rigidly with a ring (17). Furthermore, an enclosed guide duct with a guide tube (22) is provided for the roving, which guide tube (22) is supported to be pivotable about its longitudinal axis and supports a presser finger (25). Thus, a flyer of relatively low weight results, but of high solidity, permitting high rotational speeds. The guide duct for the roving can be of enclosed shape over a maximum of its length.
