Definitions

  • the invention relates to a side support for a heald.
  • Heald frames are essential parts of weaving machines. They serve for shedding by passing warp threads up or down from the warp sheet while others remain in the rest position or in the opposite direction to be moved. A weft thread is then introduced into the thus formed compartment to produce the desired binding.
  • the U.S. Patent 4,022,252 discloses such a hive. To him belong an upper and a lower, in use horizontally arranged shaft rod.
  • the shaft rods are each provided with Litzentragschienen, sit on which strands. Each strand has at least one thread eyelet through which a warp thread passes.
  • the shaft rods are connected at their ends by so-called side supports arranged approximately vertically in use, which define a rectangular frame with the shaft rods. The side supports hold the shaft rods at a defined distance from each other and also take over management tasks.
  • the from the U.S. Patent 4,022,252 known side support consists of a plastic profile body, in which a cross-sectionally U-shaped sheet metal profile is embedded. A portion of the sheet metal profile lies on the side facing away from the shaft rods side to light and serves as a guide profile for a vertical sliding of the shaft.
  • the material combination plastic / metal can be critical. Measures must be taken to prevent detachment of the metal profile from the plastic body.
  • the JP 02068331 A discloses a low weight shaft frame comprising a side support made up of an assembly of multiple layers of laminated thermoplastic materials and aluminum layers.
  • the EP 0 297 003 B1 revealed in FIG. 8 a side support in the form of a thick-walled U-profile, the profile is open on the side facing away from the shaft rods.
  • Such profiles can be produced for example by milling or extrusion of aluminum.
  • the DE 44 03 923 C1 discloses a tubular box profile-like side part, which is connected by means of Eckitatis kind with the shaft rod of a heald. To drive the weaving shank, it is proposed that the corner connecting part has a drive part connected by riveting.
  • the US 2002/004 0736 A1 discloses a side support for a heald, which is formed as a solid profile. It not only serves to support and support the shaft rods but at the same time to drive the same. For this purpose, it is provided on its side remote from the heald frames with a groove into which a threaded end rod fits. At the upper end of the side support two plates are screwed, which have a receiving slot for a connector, which is bolted to the threaded rod. The connector may also be guided vertically displaceable on a guide profile to effect guidance of the heald.
  • the slotted plates which are provided for connecting the side support with the connector and the threaded rod, are bolted to the solid profile.
  • the presented side supports are connected in their production with a considerable effort. In addition, their capacity is limited.
  • the side support according to the invention has a base body which is formed by a sheet bending profile.
  • the sheet metal bending profile may consist of a single bent sheet metal part or, if necessary, also several e.g. consist of two sheet metal bending parts. It is a hollow profile enclosing a cavity. If required, internals can be arranged in the cavity. It is also possible to provide the cavity completely or partially with a foam filling or a honeycomb structure. However, in the preferred embodiment, the like is omitted.
  • the bent sheet metal part assumes the supporting function. It connects the upper and lower shaft rods or the shaft rod connection devices provided for connecting the shaft rods to one another.
  • the side supports according to the invention can be manufactured with simple means more precise than previous side supports, which always have a certain bending elasticity and therefore must be addressed after manufacture. With the side supports made as sheet-metal bent parts, for example by punching, tolerances can be tolerated with respect to their effective length in the order of ⁇ 0.02 mm to reach. This is a significant improvement over previous side supports.
  • the cavity provided in the side support preferably extends at least over a substantial portion of the longitudinal direction of the sheet metal bending part. This is given for example by the distance between the shaft rod connection devices. It results in high stiffness, a low weight of the side supports, which not only allows the above-mentioned cost reductions in the production but possibly also an improvement in the operating speed of a loom, the heald frames are equipped with such side supports.
  • the main body of the side support forming sheet metal bending part may be formed, for example, as a U-profile and a total of one piece. It can then have an open slot on its side facing the shaft rods.
  • the shaft rod connection devices or other elements which are intended to come into contact, for example, with the healds, such as spacers or the like, protrude out.
  • the positioning and mounting of such additional elements is simple and possible due to the long open, accessible through a wide slot cavity as needed at different locations. In this way, side supports with different distances between the two shaft rods can be easily produced.
  • the side support may be prepared at a plurality of spaced apart locations for connection to the shaft rod connector. Thereby it is possible different Adjust shaft rod distances and thus different strands.
  • the cavity is preferably closed.
  • the outer surface of the side support can then serve for sliding. In addition, the risk of injury and contamination tendency are reduced.
  • the main body can also be formed by a partially closed sheet metal bent part, which starts from a U-profile, wherein the edges of the legs of the U still have sections bent toward each other.
  • a side support proves to be particularly kink-resistant.
  • the main body of the side support may also be formed by two (or more) interconnected sheet metal bending parts. These are, for example, shell-shaped and arranged with their open sides facing each other. This creates a closed side support which encloses a cavity, wherein the end faces have openings. For attachment of the shaft rod connection means corresponding cutout are provided through which the shaft rod connection devices protrude.
  • the shell profiles can be welded or riveted together.
  • a drive connection device is provided on the side support. This is formed by two flat projections parallel to each other, which join seamlessly and seamlessly to the base body, ie are connected in one piece with it.
  • the joint and seamless connection is preferably achieved by the extensions in one Piece punched out with the main body or otherwise cut out of a raw sheet. If necessary, however, they can also be welded. Where then a weld is present.
  • connection piece can be held, which serves to transmit a drive movement on the side support.
  • the connecting piece is preferably held captive on the extensions and, for example, rotatably mounted thereon.
  • a hexagonal connection piece is preferred.
  • the sheet metal bending part (or the sheet metal bending parts) is preferably made of steel. Dieiser can run in plastic guides, with steel and plastic usually forming a good friction pairing. Preference is given to stainless steel, so that surface processing, in particular corrosion protection measures can be omitted.
  • FIG. 1 illustrates a weaving shank 1 with upper and lower shaft rods 2, 3 and side supports 4, 5.
  • the shaft rods 2, 3 and the side supports 4, 5 form a rectangular frame.
  • Litzentragschienen are arranged, on which strands 6 sit. These serve to guide warp threads, to which they have corresponding eyelets 7.
  • the side supports 4, 5 are formed equal to each other and preferably arranged mirror-symmetrically.
  • the following description of the side support 5 applies equally to the side support 4. It is also possible to make the side supports different, so that e.g. one of the side supports is non-detachably connected to the shaft rods, while the other side support is detachably connected to the shaft rods.
