Support element for a heddle frame
A support element for a heddle frame is formed by profiled pieces ( 1, 1 ′) at each end that consist of a polymeric material. The profiled pieces ( 1, 1 ′) are connected to one another at each side by at least two side pieces ( 2, 2 ′) made of a metallic material. At the inside cavity of the body formed by the profiled pieces ( 1, 1 ′) and the side pieces ( 2, 2 ′) there is a separate core ( 4 ) arranged, and the inner surfaces of the side pieces ( 2, 2 ′) are provided with a layer of insulating material.
1. A support element for a heddle frame having a predetermined height, said support element comprising at least a pair of spaced apart parallel profiled pieces of polymeric material, a pair of spaced apart parallel side pieces of a metallic material secured along opposing side edges of the profiled pieces for interconnecting the profiled pieces together, the profiled pieces and the side pieces together forming a body cavity containing a separate core material, and inner surfaces of said side pieces each being provided with a layer of insulating material, wherein said side pieces have a height generally less than the height of said support element such that said side pieces are not used for structurally supporting a heddle mounting rail.
2. The support element according to claim 1 , wherein said profiled pieces are formed of fiber-reinforced polymer material, and each said layer of insulating material is substantially comprised of a fiber material.
3. The support element according to claim 1 , wherein each said layer is comprised of a fiber material containing a bonding agent.
4. The support element according to claim 1 , wherein said profiled pieces extend in a longitudinal direction of the element, are prefabricated and have reinforcing carbon fibers arranged in said longitudinal direction.
5. The support element according to claim 1 , wherein each of said side pieces comprises sheet steel having a thickness of less than 0.4 mm.
6. The support element according to claim 1 , wherein said core is comprised of honeycomb-shaped aluminum.
7. The support element according to claim 1 , wherein each said layer is comprised of glass fibers secured with a bonding agent.
8. The support element according to claim 1 , wherein each said layer is comprised of aramide fibers secured with a bonding agent.
9. The support element according to claim 1 , wherein each of said side pieces is comprised of aluminum having a thickness of less than 0.7 mm.
10. The support element according to claim 1 , wherein said core is comprised of a high-density foam.
11. The support element according to claim 1 , wherein said core is comprised of wood.
12. A support element for a heddle frame having a predetermined height, said support element comprising:
a pair of spaced apart parallel profiled pieces of polymeric material; and
a pair of spaced apart parallel side pieces of a metallic material secured along opposing side edges of the profiled pieces for interconnecting the profiled pieces together, the profiled pieces and the side pieces together forming a body cavity containing a separate core material, and inner surfaces of said side pieces each being provided with a layer of insulating material,
wherein said side pieces are dimensioned relative to the height of said support element such that said side pieces are not used for structurally supporting a heddle mounting rail.
13. The support element according to claim 12 , wherein said profiled pieces are formed of fiber-reinforced polymer material, and each said layer of insulating material is substantially comprised of a fiber material.
14. The support element according to claim 12 , wherein each said layer is comprised of a fiber material containing a bonding agent.
15. The support element according to claim 12 , wherein said profiled pieces extend in a longitudinal direction of the element, are prefabricated and have reinforcing carbon fibers arranged in said longitudinal direction.
16. The support element according to claim 12 , wherein each of said side pieces comprises sheet steel having a thickness of less than 0.4 mm.
17. The support element according to claim 12 , wherein said core is comprised of honeycomb-shaped aluminum.
18. The support element according to claim 12 , wherein each said layer is comprised of glass fibers secured with a bonding agent.
19. The support element according to claim 12 , wherein each said layer is comprised of aramide fibers secured with a bonding agent.
20. The support element according to claim 12 , wherein each of said side pieces is comprised of aluminum having a thickness of less than 0.7 mm.
