In rubber-coating apparatus including calender rollers which define a coating gap therebetween for applying rubber to a fabric web, and in which excess rubber accumulates outside the lateral edges of the web, a new type of excess rubber recovery apparatus includes a pair of excess rubber control bodies, each having the shape of a solid of revolution. Each of these bodies is suspended by a flexible rotary drive shaft from a drive unit connected by a universal joint to a carriage which is adjustable along a horizontal rail. The mechanism rotates the control bodies in a manner to displace the excess rubber toward the central region of the fabric and permit it to be conveyed back to the coating gap by one of the calender rollers.
