Claims
- 1. In a clip-chain track for tenter clips, with roller guidance in tenter frames for sheet material, composed of a clip-chain support with rod-like, endless and jointless guide rails of small cross-section mounted pairwise to the clip-chain support on both sides of the tensioning plane of the tenter chain, and with tenter clip rollers resting by their running surfaces against said guide rails,
- the improvement comprising a pair of vertical spindle means connected to a clip body of each said tenter clip and mounting separate support rollers and running rollers on both sides of a tensioning plane of a sheet material in two separate transverse planes on each of said spindle means, with the support rollers absorbing vertical forces and having slanted running surfaces of opposite inclinations, and
- separate support rails mounted on one side of their associated support rollers and running rails mounted on the other side of their associated running rollers in the said transverse planes at the clip-chain support.
- 2. A clip-chain track according to claim 1 in which the running surface of the support rollers is conical.
- 3. A clip-chain track according to claim 1 in which the running surface of at least one of the running rollers is cylindrical.
- 4. A clip-chain track according to claim 1 including catch means above the tensioning plane between the pair of running rollers and the clip body.
- 5. A clip-chain track according to claim 1 wherein said running rollers are mounted on said spindles on both sides of an in approximately mirror-symmetrical manner with respect to the tensioning plane of the sheet material, said rollers resting against a pair of rails facing the length of material and absorbing transverse tensional forces, and said support rollers comprise at least one additional roller mounted on each spindle and resting against a rail mounted on the chain track support away from the length of material.
- 6. A clip-chain track according to claim 1 in which said support rollers absorbing vertical forces are mounted pairwise and in approximately mirror-symmetrical manner with respect to said tensioning plane and have slanted running surfaces of opposite inclinations.
- 7. A clip-chain track according to claim 1 in which a support roller is mounted on one of said spindles below the tensioning plane of the sheet material and a support roller is mounted on the other of said spindles above said tensioning plane, said support rollers having slanted running surfaces of opposite inclinations, and said associated support rails being mounted on the chain track support away from the length of material.
