Definitions

  • the invention relates to a circular loom with the features of the preamble of claim 1.
  • Kettbmixchen guide elements are arranged around the Rundriet around, which are designed to supply a plurality of Kettbisserchen to the circular loom.
  • Web training facilities group the supplied warp ribbons into two sets of warp bands and give them opposing alternating movements, whereby a shed between the two Kettbändchenscharen is opened and closed. A shooter moves in an orbit in the open shed and thereby enters a weft ribbon in the shed, whereby a tissue is formed.
  • the fabric is pulled off through a Webring.
  • several weaving machines usually run simultaneously in a respective shed in a round pile.
  • a cam holder On the main shaft of the loom a cam holder is formed, which has at least one undulating around the cam holder circumferential cam, and around the cam holder around control levers are arranged, which engage with one of its ends in the at least one control cam.
  • the ends of the control lever is given a deflection movement, which are transmitted by the control lever gegentechnisch equal to the shed forming means whereby this is given a reciprocating motion and wave-shaped sheds are formed in the circumferential direction.
  • a cross section of a wave-shaped shed in the circumferential direction parallel to the main axis substantially corresponds to the cross-section of a convex lens.
  • two control levers are usually provided per shed forming means.
  • Assign the shed forming means for guiding the Kettbändchen by a stretched around two pulleys band with eyelets usually only one control lever is provided per shed forming device.
  • a circular loom with shed forming devices with half shanks is known, for example, from the document IN 159848 A1.
  • a circular loom with shed forming devices with a tensioned around two pulleys band is for example from the document EP 2 829 645 A1 known.
  • the shed forming means of the circular loom according to the invention comprise a plurality of pivot elements and the Kettbändchen leading Kettfadenhubstoff, wherein each pivot member is connected to at least two, preferably a plurality of Kettfadenhubstoffn.
  • each pivot member pivotal movement about a substantially radially to the main axis arranged pivot axis and a lifting movement.
  • the Swivel elements issue the Kettfadenhubstoffn depending on the gradient and thus the course of the at least one control cam by the pivoting movement and the reciprocating motion changes, whereby the shed is opened and closed.
  • a pivot axis extends centrally through a pivoting element.
  • pivot elements can either be coupled directly to the at least one control cam, or that the pivot elements can be coupled via connecting elements, such as levers, rods or gears with the at least one control cam.
  • substantially radial to the main axis means that the pivot axes of the pivot elements can also be arranged slightly inclined to axes arranged radially to the main axis.
  • the circular loom according to the invention comprises shed forming means, which are very simple in construction and form a shed-shaped shed in cross-section.
  • the circular loom invention is not only very efficient, but also low maintenance and economical in operation. Due to the lenticular cross-section of the shed / sheds, the number of shuttlers simultaneously circulating in the round shave can be maximized or, with the same number of shovers, the distance between the shifters and the warp bands at the ends of the shed / sheds can be increased. whereby the risk of collisions of the weaver with Kettbändchen is reduced and thereby conditional Kettbändchenrisse be avoided.
  • the circular loom according to the invention can be operated at a higher speed than conventional circular looms. Furthermore, the advantage obtained by the lenticular shed that the gradient of the cam at the ends of the shed may turn out lower than step-shaped sheds, which leads to lower accelerations at deflections of moving parts, whereby the production speed of the circular loom according to the invention can be further increased and the moving parts are spared.
  • the course of the at least one control cam in the circumferential direction substantially corresponds to the course of the shed.
  • the course of the shed can be adjusted very easily by changing the at least one control curve.
  • the at least one control cam is formed by a groove, a groove or a protruding web.
