Apparatus for molding material including a frame for holding the material and which is movable away from the molding die so that the material can be loaded and unloaded into and out of the frame at positions clear of the die. The frame has spring biased movable mountings having pins which penetrate the material and hold this in a resilient manner during molding. A turntable support is provided for holding two of the frames on opposite sides of a vertical axis, and this holds one frame in a convenient loading position while the other frame is holding material being molded.

Holding means for holding material during forming by a die, comprising two substantially flat parts each with a pair of apertures which are hinged together so as to be movable from a closed condition in which the apertures are in register so forming a common pair of apertures and in which a piece of material may be held between said parts to extend across said common aperture, to an open position in which material may be loaded and unloaded into and out of the holding means, and wherein one of said hinged parts has spring biased movable mountings carrying pins which are surrounded by the substantially flat area of the respective part and project towards the other of said hinged parts so that in the closed position the pins penetrate and hold material which is held substantially flat between said parts, said pins being spaced apart around each of said apertures and being movable towards their respective aperture of the one part against a spring resistance at least some of said pins being located between said apertures and being movable away from each other as they move toward their respective apertures.
