Definitions

  • ABSTRACT A support rod for a harness frame of a loom and method for the fabrication of such support rod wherein at least one edge reinforcement means is mounted at the region of at least one of the extremities of a lightweight support rod body member, with a thermally hardenable adhesive material interposed at the interface between the edge reinforcement means and the body member. A force is applied to said edge reinforcement means and said body member sufi'icient to firmly clamp such edge reinforcement means and body member to one another while preventing relative shifting of .said edge reinforcement means and body member.
  • body member and edge reinforcement means are then heated to a temperature sufficient to set the adhesive material while maintaining the clamping force to prevent relative shifting of said edge reinforcement means and body member.
  • the body member and edge reinforcement means are then cooled down to room temperature while still maintaining the clamping force to further prevent shifting of the edge reinforcement means and body member relative to one another, in
  • The'present invention relates to anew and improved harness frame support rod or -rail:for-. looms possessing increased bending strength or structural rigidity, and also is concerned with a novel-method forthe fabrication of such inventive harness frame support rod.
  • Still a further significant object of the present invention relates to a novel, construction of heddlesupport rod for the harness frames of looms possessing increased bending strength, yet relatively low weight.
  • a further significant object of thepresent invention relates to an improved constructionxof support rod or rail for the harness frames of looms formed from a lightweight body member equippedwith reinforcement means at least at one of the extremities of the support rod, the reinforcement means beingformed of amaterial possessinga considerably greater'modulus of elasticity than the modulus of elasticity of the material forming the lightweightsupport rod body.
  • the support rod for a loom harness frame as contemplated by this invention comprises a support rod body member formed of a lightweight material possessing relatively low modulus of elasticity.
  • the body member includes external edgesor edge regions spaced furthest from the neutral bending axis of such body member, reinforcement means being secured to such external edges.
  • the reinforcement means exhibit a total cross-sectional area which is small in relation to the cross-sectional area of the body member.
  • the cross-sectional area of such reinforcement means preferably amounts to no more than approximately one-fifth of the crosssectional area of the solid material of the harness frame body member and no more than approximately onetwentieth of the total cross-sectional area of the body member.
  • Each such reinforcement means is advantageously formed of a material different from the material of the body member and possesses a relatively high modulus of elasticity in relation to the modulus of elasticity of the material forming the body member.
  • the modulus of elasticity of the material forming the reinforcement means is preferably at least approximately three times as large as the modulus of elasticity of the material forming the support rod body member.
  • the invention is also concerned with a novel method of fabricating such new and improved construction of harness frame support rods for looms.
  • the reinforcement means are-securely bonded in a stress-free fashion to the support rod body member. This is important inasmuch as the materials forming the reinforcement means and the support rod body member differ from one another and therefore, possess different coefficients of expansion and contraction. Hence, if measures were not otherwise undertaken to provide a stress-free adhesive bond between these different materials during thermal bonding such materials would elongate and contract at different rates.
  • the invention contemplates prevention of relative displacement or shifting of the reinforcement means and body member during the heating and subsequent cooling operations by physically restraining or confining such members.
  • a pasty or liquid thermally hardenable adhesive bonding agent typically a commercially available epoxy resin which sets or hardens at elevated temperatures, typically above 100C, is provided at the interface between the reinforcement means and support rod body member. Sufficient pressure is applied for the purpose of tightly clamping the reinforcement means and body member to one another so no relative shifting occurs.
  • This assembly is then heated, for instance to a temperature in the range of 110 130C, the bonding agent hardening at the elevated temperature, typically for instance at 120C. Then such assembly is permitted to cool down. Owing to the imposed restraint against relative elongation and contraction of the reinforcement means and body member during the heating and cooling of these components the adhesive bond can set without being subjected to any appreciable shearstresses. As a result, there is produced a good firm stress-free bond between these components, promoting high operating speeds of the loom without any great danger of disconnection or rupture of this bond of the heddle support rod, which otherwise could cause heddle failure and loom breakdown.
  • reinforcement means and rod body member can be achieved in a number of different ways.
  • One specific technique which may be employed is to provide an excess length of the reinforcement means and support rod body member, then to fixedly interconnect these members to one another, as by riveting, to prevent relative shifting or displacement.
  • the adhesive bond at the interface between these members is then permitted to set at elevated temperatureswhile a clamping force is applied between the members, and thereafter the assembly is permitted to again cool down to room temperature.
  • the excess length of the reinforcement means and body member which contains the connection rivets is cutaway so that the harness frame construction is then of desired size.
  • Another preferred technique which can be successfully practiced is to clamp the entire assembly of reinforcement means and body member, with the thermally hardenable adhesive material at the interface therebetween, in a press and to apply sufficient clamping pressure to this assembly of components so as to prevent relevant shifting i.e., elongation and contraction of the reinforcement means and body member during the heating and subsequent cooling operations.
  • the adhesive material is then permitted to set at elevated temperature and the assembly cooled down to room temperature, producing the stress-free bond between these components.
  • Such adhesive materialconfining means can be in the form of raised spacer ribs located at the interface between these components, and preferably at each of the recesses of the support rod body member receiving one of the reinforcement means.
  • spacer ribs take-up the forces exerted during the clamping operation so that the clamping pressure is distributed to a large extent over such spacer ribs, thus ensuring that the adhesive material in the recess or recesses at the interface between these abovementioned components will not be expressed out of such recesses, rather will set thereat to provide the desired bond.
  • an open glass fiber fabric or web for instance of about 0.2 mm. thickness, imbued with the adhesive material and providing the same function as the spacer ribs discussed above.

In any event this force or pressure must be sufficient to tightly clamp the reinforcement elements with the body member of the support rod so as to prevent any relative displacement or shifting between these components during the expansion and contraction occuring by virtue of the heating and cooling operations. For instance, when using a 1 mm. thick reinforcement element and the spacer ribs a clamping pressure in the range of approximately 50 100 kp/cm, based upon each square centimeter of surface area of the reinforcement plate i.e. adhesive location, has been found to be satisfactory.
