Abstract
An assembly for curing a linear work product which is passed through a curing oven at high speed along a first path the assembly having a first path altering member, such as a sheave, re-directing the work product through the oven along at least a second path spaced from the first path. A plurality of such sheaves in a first embodiment redirect the work product through the entrance end of the oven for travel along a second path in the same direction as in the first path. In a second embodiment, the path altering members re-direct the work product into the exit end of the oven for travel in a second path in the opposite direction to the first path. Additional curing may be realized by passing the work product through the curing oven in the same or in opposite directions, as desired or as necessary.
