Abstract
A hot melt carpet seam roller comprising a handle. At one end of the handle is disposed a support member with an opening. Received by the opening in the support member is an axle. The axle is divided into two sections. Each section of the axle is directed away from the handle at an angle approximately 5.degree. from the axis of the opening formed in the support member so that the converging angle therebetween is approximately 170.degree.. A first set of nylon discs is mounted on one section of the axle with the axes thereof coincident with the axis of the one section of the axle. A second set of nylon discs is mounted on another section of the axle with the axes thereof coincident with the axis of the other section of the axle. The peripheral surface of each disc is formed with radially disposed, angularly spaced teeth. When the roller is used behind a hot melt iron, the roller presses a carpet into the molten hot melt adhesive. The angularly disposed sections of the axle enable the discs to draw contiguous carpets forming a seam closer together and cause the adhesive to draw up to the seam joint at the location of the separation.
