Carpet Seaming Roller, from the Roberts tools stable, our spiked seaming roller helps carpet fitters produce an invisible joint  in carpet seam. Used by the carpet fitter while heat seaming (see RWS055 and RWS051)

The three sets of spiked rollers groom the carpet fibers to form a perfect seamed joint. A must for all carpet fitters'  tool boxes. We also stock the solid wheel seaming roller from Roberts, these are designed to maximize adhesive transfer to the carpet backing and are also great for use on vinyl sheet seams and edges. See RWS062A
