Abstract
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.
Claims10
The combination comprising:
- a turntable having means for fixedly supporting a work piece;
- means supporting said turntable for rotation about a rotational axis and for movement in a plane extending in a direction transverse to said rotational axis, said supporting means including a support arm and means supporting said arm for swinging movement about an axis normal to said plane, said turntable being rotatably supported by said support arm at a location remote from said last mentioned axis;
- a cam wheel connected to said turntable for rotation therewith and for movement therewith in said plane;
- said cam wheel having a peripheral edge surrounding said rotational axis at varying distances therefrom;
- a drive means having a portion moving at a constant linear speed in driving engagement with said peripheral edge of the cam wheel at a fixed first location in said plane;
- and
- means yieldably urging said cam wheel into peripheral driven engagement with said drive means.
