Title: Willowing machine needle bars - are angled at ends to take clamping wedge between bars without distortion
IPC: D01G11/00
Filed: 1991-09-19
Abstract: The carrier bars for the needles of the drum, of a willowing machine, are angled at their ends, to form a V-shaped cross section between bars, opening radially outwards. The wedges lie over the whole angled surfaces of the bar ends, only at the sides. The wedges are pref. secured to the drum by mounting screws, within the wedge cross section of the wedges, through drillings within the wedges. Threaded drillings are in the mantle wall of the drum to take the mounting screws inserted through the wedges from the outside. The screw heads have a smaller dia. and width than the wedge at its outer closing surface which, when fitted, is below the outer surface of the neighbouring carrier bars, to ensure that the bars are only clamped by the sides of the wedges. Some wedges, pref. alternate wedges, cannot be removed. The wedge side surfaces define the cross section of the wedge, on every plane at right angles to the central axis and also on the theoretical extension of the opening section, to form the max. cross section of the wedge. A drilling through the wedge, at right angles to the width, takes the mounting screw, without passing through the side surfaces. The wedge gives upper and lower surfaces. The side surfaces of the wedge form an included angle so that the side surfaces match the thickness of a carrier bar on either side of the drilling through the centre of the wedge. ADVANTAGE - The carrier bars are held in place without distortion of their ends, or damage to the drum, with easy dismantling.
Patent DE-4131656-A1 (DE)
Inventor: JOSEFSSON PAER
IPC: B65H59/26
Filed: 1991-09-23
Abstract: According to a process for controlling the insertion process of a weft yarn, the weft yarn is temporarily exposed to a braking friction and the yarn tension is mechanically picked-up. In order to prevent the friction from having a disturbing or damaging effect on the yarn, the yarn tension is only temporarily picked-up during certain phases of the insertion process, in order to derive from the tension curve informations that is useful for the control. In a power loom, in particular a jet, rapier or gripper shuttle loom, a tension sensor for sensing the tension of the weft yarn can be switched during insertion between its sensing position and a passive position in which it does not touch the weft yarn. Appropriately, the tension sensor is integrated in the insertion brake or even forms the braking element itself.

Title: Adjusting printing pressure in printing machine - involves separate mechanisms to adjust plate cylinder and blanket cylinders
Inventor: JENTZSCH ARNDT
IPC: B41F13/34
Filed: 1991-12-23
Abstract: The printing machine has members which enable the pressure between plate cylinder and blanket cylinder and the pressure between blanket cylinder and printing cylinder to be separately adjusted.
