This invention relates to a mold for the covering and trimming of plastics products, particularly of panels for the inside upholstery of motor vehicles. The object of the invention is to avoid that the covering material (4), spread over a heated sheet of plastics material intended to constitute the product (3) to be covered, may be pinched between two side knives (8) associated with two substantially rectilinear sides of the outline of the product (3) and converging to each other toward a preferably rounded corner of said product (3). To achieve this object, at the angle between the two side knives (8) associated with the converging substantially rectilinear sides, there is arranged a knife (8') which is shaped correspondingly to said corner, and the ends of which slidably engage the outer planar surfaces of tapered end extensions (108) of the side knives (8). Means (9, 9', 10, 10') are provided for displacing simultaneously the side knives (8) and interposed shaped knife (8'). The sliding surfaces between the extensions (108) of the side knives (8) and interposed shaped knife (8') are at such an angle to the directions of movement of either the two side knives (8) and the interposed shaped knife (8') as to always remain in contact with each other during the movement of said knives.
