A turntable is supported for rotation as well as for radial movement in a plane transverse to its rotational axis so that, while rotating, the periphery of a non-circular cam wheel which rotates together with the turntable may be maintained in operative driven engagement with the periphery of a drive wheel which is rotated at a constant angular velocity. A material extruding nozzle is positioned to extrude gasket forming material onto a work piece carried by the turntable at a fixed location which is in registry with the point of driven engagement between the drive wheel and the cam wheel, so that the material is uniformly applied to the work piece in a path which conforms to and is in registry with the periphery of the cam wheel.
