Abstract
A carpet seaming roller tool for drawing two sections of carpet together in a hot melt adhesive seaming operation has two, separate, cleated rollers which are disposed side-by-side so that one roller grips one section of carpet and the other roller grips the other section of carpet as the roller tool is rolled back and forth along the seam during the seaming operation. Each roller has an axle which is mounted for rotation about a horizontal axis in its own support frame, and each support frame is mounted for a limited amount of pivotal, swinging movement (about a generally vertical axis) in a main frame associated with the handle of the carpet seaming roller tool. Because the axles are independently pivoted for a limited amount of swinging movement both forward and rearward of a position of exact axle alignment, the roller tool can be pushed and pulled along the seam while the axles automatically swing to positions which draw the two sections of carpet tightly together during both directions of movement of the carpet-roller tool.
