Definitions

  • the present invention relates to heald frames which are mounted on the looms and which are connected to a dobby or other mechanical for the formation of the crowd, for the production of a fabric in accordance with the desired reinforcement.
  • these frames are constituted by the assembly of four separate elements, namely two superimposed horizontal crosspieces and two lateral uprights, the edge of said crosspieces which is turned inwards being equipped with a rail for fixing the hooks provided. at the ends of the thread guide bars.
  • the upright-transom assembly arranged at each of the angles of the frame is established in easily removable form and the present invention is based precisely on the observation that the choice of the assembly method is more delicate than it may seem at first glance.
  • each upright has a nose which projects laterally on the wall of said upright turned towards the inside of the frame and whose horizontal edges form clean enough to cooperate with a fixed part and a leaf spring, these two parts acting in the manner of jaws using a clamping screw to immobilize the aforementioned nose.
  • the invention consists in defining the bearing surfaces against which the jaws apply, by the edges of at least one opening made in the wall of the upright which faces said jaws, so that these bearing surfaces are arranged inside. of the section of the upright in order to avoid any bending moment at the level thereof.
  • the reference 1 designates one of the two ends of the upper horizontal cross member of the frame in question, which cross member is formed, in the manner known per se, by a hollow profile stiffened by internal horizontal partitions.
  • a fixed jaw 2 provided with a horizontal bead 2 has locked in place using the two screws 3 which ensure the fixing of the ear vector 4 (not shown in fig. 1) intended for mooring the pulling member associated with the dobby.
  • the jaw 2 has a projecting beak 2 b capable of forming a clamping jaw, as will be better understood below.
  • the mouthpiece or movable jaw 5 is provided at the end of a tilting jaw suitably profiled 5 and joined to the fixed jaw 2 by a screw 6, as illustrated in fig. 2 and 3.
  • the jaws 2 b and 5 a define between them a housing 2 c which has in section a substantially trapezoidal profile whose small base is turned towards the outside of the considered end of the crosspiece 1.
  • This housing 2 c is intended to accommodate an assembly member 7 a having the same trapezoidal profile, which member is integral with the upper end of the corresponding upright 7 of the heald frame.
  • this upright 7 having a U-shaped profile in section, is cut at its central veil, with an opening 7 b which thus defines the member 7 a mentioned above, which has two opposite bearing surfaces 7 c oriented obliquely to cooperate with jaws 2 b and 5 a .
  • this method of assembly is advantageously adopted at the four angles of the heald frame which, despite its resistance to deformation, is capable of being easily disassembled with a view to replacing the usual yarn guide hoses engaged on a horizontal rail 8 provided immediately below or above the internal horizontal edge of each cross member 1.
  • the assembly and disassembly operations are simplified since they only require the operation of a single screw 6 at each of the heald frame angles, being observed that this screw is able to be easily made captive.
  • the uprights 7 can have any desired profile in section, the U-profile envisaged above having been indicated only by way of example.
  • the fixed jaw here referenced 12, comprises a beak or jaw 12 b turned upwards, while the beak or jaw 15 a of the movable jaw 15 is turned downwards.
  • the two jaws 12 and 15 are connected to each other by a spring 19 which tends to apply the movable jaw 15 against the internal partition 1 a of the cross member, and it is understood that the beaks or jaws 12 b and 15 a are suitable for being introduced into an opening 17 b of the adjacent upright 17.
