Definitions

  • the present invention relates to mechanics for forming the crowd on weaving machines, the term "mechanical” including both the dobbies whose armor program is likely to be easily modified, as the simplified mechanisms with cams or similar, purely repetitive.
  • these armor mechanics comprise an equal number of actuating assemblies (assemblies generally designated by the name of "blades") which are arranged in parallel to each other and each of which is formed by a series of oscillating members which cooperate with each other in order to provide, at the appropriate time which is a function of the weave desired for the fabric to be produced, the force necessary for movement vertical of the corresponding heald frame.
  • the nature and shape of these oscillating members vary according to the different types of mechanical, but we can remember that they are most often levers, connecting rods or rods, hooks, roller holders, etc ... animated by an angular movement of a defined amplitude.
  • the identical oscillating members of the different blades are mounted on a common support pin fixed in the frame.
  • the simplest assembly is that according to fig. 1, in which the fixed axis 1 directly supports the oscillating members 2, arranged side by side without any separation. Under these conditions, it is clear that these members 2 rub against each other, the friction thus generated causing overheating, significant wear and the appearance of weaving faults.
  • the present invention intends to remedy, and this by means of a solution which allows the hub of the oscillating members to rub directly on a smooth-walled shaft, thus devoid of any groove, and which nevertheless ensures the individualization of said organs in order to prohibit any mutual lateral friction thereof.
  • the subject of the invention is the armor mechanics which is defined in claim 1. Additional characteristics of the invention are defined in claims 2 to 4.
  • the invention essentially consists in operating the separation of the adjoining oscillating members using annular spacers which are engaged on the support axis between said members and which comprise, on at least one of their lateral faces, projecting bosses capable of coming into contact with the adjacent spacer, defining between these two spacers a sufficient free space for the oscillating mounting of a member.
  • FIG. 4 there is shown at 5 a spacer which is pierced with an opening 5 a forming a hub, an annular projection 5 b being advantageously provided on each of the lateral faces of said spacer around the outlet of this opening 5 a .
  • the spacer 5 is integral with an extension 6 in the form of an arm which is pierced at 6 a at a diameter much smaller than that of the opening 5 a , this bore 6 a being similarly bordered by two opposite annular projections 6 b .
  • bosses 7 are provided which protrude laterally on one and the other of the opposite faces of said part.
  • the spacer 5 had four protruding bosses 7 while the arm 6 carried only one.
  • Fig. 5 and 6 illustrate the mounting of parts 5-6 and of the oscillating members 2 on the common support axis 1.
  • the members 2 are constituted by hooks which under the action of the reading device of the mechanical (action which has been shown in the form of opposite arrows f ), are intended to come to be coupled with fixed hooks 8 corresponding, or to escape the latter, and this by means of an oscillation of reduced angular amplitude.
  • a part 5-6 Between two adjacent members or hooks 2 is interposed a part 5-6, the arm 6 of which is engaged by its bore 6 a on a rod 9 fixed in the frame of the machine being oriented parallel to the axis 1, the position of this rod 9 being such that the set of spacers 5 is angularly retained so that the main part of the hooks 2 and their actuating tail 2 a are located between the bosses 7, enjoying sufficient angular freedom for their oscillation.
  • the bosses 7 of two adjoining parts 5-6 can therefore come into abutment, ensuring the correct spacing of the hooks 2.
  • Each oscillating member or hook 2 rubs directly on the support axis 1 provided with a smooth wall.
  • the mounting of these hooks and parts 5-6 on this axis 1 presents no difficulty and can be carried out using simple automatic machines, with high efficiency.
  • bosses 7, their arrangement and their sectional profile can vary to a very large extent.
  • each part 5-6 are capable of extending only on one side thereof, provided that they are provided long enough to come to bear against the smooth face of the adjacent room.

Claims (3)

  1. Schaftmaschine für die Fachbildung bei Webmaschinen, von der Art, die zur Betätigung der mit ihr gekoppelten Schaftrahmen eine entsprechende Anzahl Betätigungseinheiten umfaßt, die parallel zueinander ausgerichtet sind und von denen jede gebildet wird durch eine Serie Schwingorgane (2), Seite an Seite auf gemeinsame Trägerachsen (1) montiert, dabei jedoch getrennt voneinander, um jede gegenseitige seitliche Reibung zu vermeiden,
    dadurch gekennzeichnet,
    daß die Trennung der Schwingorgane (2) bewirkt wird durch ringförmige Abstandsstücke (5), die zwischen besagten Schwingorganen auf der Trägerachse (1) sitzen und die auf wenigstens einer ihrer Seitenflächen vorstehende Höcker (7) aufweisen, die Kontakt haben mit dem benachbarten Abstandsstück, wodurch zwischen den beiden Abstandstücken ein freier Raum definiert wird, der ausreicht für die schwenkbare Montage eines Organs (2).
  2. Schaftmaschine nach Anspruch 1, dadurch gekennzeichnet, daß jedes Abstandsstück (5) versehen ist mit Einrichtungen (6), die seine Winkelhaltung auf der Trägerachse (1) sicherstellen.
  3. Schaftmaschine nach Anspruch 2, dadurch gekennzeichnet, daß jedes Abstandsstück (5) aus ein und demselben Stück ist wie ein Arm (6), der eine Bohrung (6a) aufweist für seine Montage auf der Rückhaltestange (9), die befestigt ist im Gestell der Schaftmaschine, parallel zu der Tragerachse (1).
