An apparatus for feeding a flexible elongate member, e.g. pile weatherstrip, into a groove in an elongated member, the apparatus being capable of being driven by an electric motor or drill and including a pair of rollers defining a nip through which the pile is driven into an outlet guide with which the groove in the elongated member is aligned at the downstream end thereof. It is preferred that two sets of roller nips are provided, there being a common roller for each nip and there being an inlet guide to direct the pile weatherstrip into a first nip, and an intermediate guide to direct the weatherstrip from the first nip to the second nip and hence into the outlet guide. Preferably, the roller common to each pair is driven via a toothed belt, and the other two rollers can be moved towards or away from said common roller. Preferably, this roller has a grooved periphery to receive the pile of the weatherstrip and all the rollers are knurled.
Apparatus for feeding an elongate flexible member, e.g. pile weatherstrip, into a groove in an elongated member, the apparatus comprising a frame, a pair of contra-rotating pile weatherstrip advancing rollers mounted on said frame and forming a first nip, a third pile weatherstrip advancing roller, means mounting said third roller on said frame so that it forms a further nip with one of the rollers of said pair, means to drive all of said rollers, means to guide the pile weatherstrip through said further nip of said rollers so as to increase the forces acting on the pile weatherstrip to advance it into the groove, means to guide the pile weatherstrip into and through said first nip of said pair of rollers, and an outlet guide downstream of the further nip of the third roller and one of said pair of rollers to receive the pile weatherstrip as it emerges therefrom, the arrangement being such that the groove in the elongated member can be aligned with said outlet guide to receive the advancing pile weatherstrip.
