Abstract
A traction tensioning device which has one or more upper chain assemblies driven by an upper sprocket pulley and one or more lower chain assemblies driven by a lower sprocket pulley. Each of the upper and lower chain assemblies has a plurality of pads mounted to the chain assemblies. The upper chain assembly is mounted to a movable platen. The lower chain assembly is mounted to a fixed platen. The upper chain assembly and the movable platen are raised and lowered with respect to the lower chain assembly thereby creating a tension on a strip of material passing between the upper and lower chain assemblies.
Claims20
A traction tensioning device comprising:
- at least one upper chain assembly driven by an upper pulley;
- at least one lower chain assembly driven by a lower pulley,
- wherein each of said at least one upper and lower chain assemblies comprises a plurality of pads mounted to said chain assemblies;
- wherein said upper chain assembly is mounted to a movable platen member;
- wherein said lower chain assembly is mounted to a fixed platen member;
- wherein said upper chain assembly and said movable platen member raises and lowers with respect to said lower chain assembly thereby creating a clamping force on an associated strip of material passing between said upper and lower chain assemblies.
A traction tensioning device comprising:
- at least one upper chain assembly driven by an upper sprocket;
- at least one lower chain assembly driven by a lower pulley,
- an upper movable track member and a lower movable track member, wherein said upper chain assembly engages said upper movable track member and said lower chain assembly engages said lower movable track member, wherein at least one of said upper movable track member and said lower movable track member is moved to provide tension to its respective chain assembly.
