A threshold mat comprising alternating scraper units (2) and wiper units (1). The improvement is that the wipers (1), that is strips of carpeting are carried on extrusion carriers (3) and are gripped by their edges via a tightenable clamp incorporated in the scraper unit. The feature of tightening enables different thicknesses of carpet material to be accommodated. <IMAGE> |
