ABSTRACT:
Disclosed is a device to convey parts towards one or more processing stations and to remove them therefrom. This device includes a rail forming a continuous closed circuit and supporting a series of supports which are in contact with the rail by rollers, at least one of which is elastically biased against the rail. Each support is provided, at least at one of its ends, with a ball bearing or roller bearing, by which each support comes into contact with the support that precedes it or follows it. Preferably, the rail has a section with two opposite cants, and it is elastically gripped between rollers having a groove with a shape that matches the cants. Thus, precise positioning is obtained in the transversal direction of each support with respect to the rail, and the ball bearings provide precise contact, with low wear and tear, between two successive supports. This provides for accurate positioning also in the longitudinal direction.
