Abstract
An apparatus is described for securing an edge of the material to a support surface. A guide surface is positioned adjacent the edge to be secured. A weld head engages the edge of the material in a plurality of locations. A drive mechanism advances the weld head on the guide surface. The weld head engages the edge of the material and transfers energy to secure the edge of material in the desired position on the support surface.
Claims16
An apparatus for securing an edge of a material to a thermoplastic surface comprising:
- a guide mechanism positioned adjacent the edge to be secured, the guide mechanism being disposed to engage the edge of the material to fold the edge of the material over an edge of the support surface;
- a carriage moveably positioned adjacent the guide mechanism;
- a drive mechanism to advance the carriage on a guide surface and a weld head positioned on the carriage, the weld head disposed for engaging the edge of the material, the weld head designed to contact the edge of the material in a plurality of spaced apart locations, the weld head transferring energy to the areas of the edge of the material that is contacted by the weld head to secure the edge of the material in the desired position on the support surface;
- and
- a guide disposed for engaging the folded edge of the material to assist in holding the material in place against the support surface while the material is engaged by the weld head.

A method for securing an edge of a thermoplastic support surface comprising:
- positioning a guide surface adjacent the edge to be secured, engaging the edge of the material with the guide mechanism to fold the edge of the material over the support surface;
- advancing a weld head with respect to the guide surface, the weld head engaging the edge of the material as the weld head is advanced, the weld head contacting the edge of the material in a plurality of spaced apart locations;
- transferring energy from the weld head to the areas of the edge of the material contacted by the weld head to secure the material to the support surface, and;
- engaging the fold edge of the material with a guide, the guide assisting in holding the material in place against the support surface while engaging the material with the weld head.
