Definitions

  • the invention relates to a shaft rod for heddle shafts of looms.
  • shaft rods for the construction of WebMften to form hollow profiles, with reinforcing strips are provided.
  • CH 525 352 discloses a Such shaft rod in the form of a light metal hollow profile, At the edges reinforcing rods made of high quality Steel are glued. Gluing the steel profiles in corresponding recesses of the light metal hollow profile a careful work process in which the Steel profile until the adhesive on the light metal hollow profile is to fix.
  • the shaft rod according to the invention is essentially formed by a profile body, with an additional profile body connected is.
  • the connection is a glue joint, over the the additional profile body as large as possible is connected to the profile body.
  • the peculiarity of Shaft rod according to the invention is a locking means, with the the additional profile body on the profile body in a desired position fixed and thus secured as long as the glue joint not yet cured.
  • the profile body and the additional profile body are mutually preferably designed to be complementary as far as one of the two bodies has a recess and the other one both bodies have a matching projection. At Place a projection of one of the involved bodies, the can also engage in a recess of the other body the additional profile body itself in a corresponding recess inserted and thus engaged. All embodiments is so far in common that through the interaction the profile of the profile body with the profile of Additional profile body formed a snap connection is a force and / or positive fixation of Adhesive joint makes.
  • the profile body and / or on the additional profile body at least one Projection, for example in the form of one or more longitudinal formed by continuous strips or ribs, which are the glue line reach through and thus a linear or strip-shaped Form contact surface, where the bodies together issue.
  • Projections thus determine the thickness the glue joint, which in this way is reliable and without additional assistance can be safely set. It can be avoided both too wide and too narrow adhesive joints become. The thickness of the glue joint is for the strength the adhesive bond crucial. Through these projections thus the quality of the final product is ensured.
  • the locking means is preferably designed so that it puts pressure on the glue joint.
  • the profile body and the additional profile body are then independent of whether the Adhesive is already cured, backlash together held.
  • the play-free holder or storage is achieved by the latching means the additional profile body on the Tightening profile body to a certain extent. This also opens the ability to leave the glue line open, i. without Get along with adhesive, e.g. if it. at the additional profile body only a cover profile is.
  • legs of the profile body enclose legs of the profile body the additional profile body or sections of the same c-shaped and thus draw it into the mouth formed by them in and in this firm, when he is in between the Thighs remaining receiving space is introduced.
  • These Legs or other locking means then have at least one inclined to the direction of insertion and pointing into the interior Pressure surface, which acts in the insertion direction Force exerts on the profile body to this against a contact surface to press.
  • the measure is that on the additional profile body, on the Profile body or between both at least one receiving space for excess, displaced from the glue line Adhesive is provided. Avoids such a receiving space, that overflowing adhesive escapes and removes must become. This, too, counteracts manufacturing security.
  • the profile body is for example by a light metal profile, for example, an aluminum extruded profile, educated. However, he can also by a plastic hollow profile or another profile, for example formed sheets are formed.
  • the additional profile body is used for example, the reinforcement and can as a full or Hollow section of suitable materials with different E modules are produced.
  • the Additional profile body a steel body, a CFRP body (fiber reinforced Plastic body) or the like.
  • fast-running shafts come with CFRP round profiles very high modulus of elasticity in question.
  • slow running Shafts can use tubular steel profiles or CFRP round profiles a lower modulus of elasticity can be used.
  • At very low Strains can also be a plastic pipe profile as Dust cover clipped into the receiving space of the profile body become. It is then secured by the locking means. A bond can be omitted.
  • the additional profile body glue on the entire length of the profile body. In many cases, but it may also be sufficient, the additional profile body only in sections with the profile body too stick together, for example at its ends or in short, spaced sections.
  • a heddle 1 is not further for one illustrated loom illustrates.
  • the weave is formed by a frame to which an upper shaft rod 3, a lower shaft rod 4 and side supports 5, 6 belong. Between the shaft rods 3, 4 strands 7 are held, with their end loops 8, 9 on Litzentragschienen 11, 12 sit. The latter are held on the shaft rods 3, 4.
  • the strands 7 serve to warp threads through the eyelets 14 to move up or down to to form the shed.
  • the shaft rod 4 is essentially a profile body 15 e.g. in the form of an aluminum extruded profile educated.
  • the profile body 15 is a hollow profile body with one or more chambers 16, 17, after outwardly largely or completely closed and hollow, i. empty or with a plastic foam or another Filler are filled.
