  • Patent number: 5108245
    Abstract: A handling unit for axially transporting elongated objects from a first location to a second location such as from a feed table into a machining unit where machining operations are to be performed upon the object. A feed table, or corresponding depository, supports a plurality of the objects to be transported in parallel relationship, and provision is made to advance the objects so that a single object is placed in a pickup location. An axially movable push rod then engages the end of the object when desired to accomplish the axial transport. This push rod is operated by a rod-less cylinder such that the cylinder and the push rod are in parallel alignment thereby reducing the length of the device to the length of the cylinder. Various embodiments are described, together with that of an "unloader" to receive the objects after machining and place them on a receiving table or the like.

  • Patent number: 4898501
    Abstract: A rotary drilling machine for forming holes of selected size and spacing in continuous strip material such as elastomeric gasket stock used for the manufacture of gaskets for door openings and the like. This machine has a rotary drum unit which carries the strip material along a portion of its peripheral edges. A plurality of drilling units are mounted on this drum unit so as to move with the strip material. The drilling units are oriented toward the peripheral edge, and these drilling units are moved radially in a proper sequence whereby drill bits thereof move toward the strip material to dril the holes and then retract. Tensioning elements produce friction between the strip material and the periphery of the drum unit to accomplish the movement thereof in unison. The tensioning elements, in a preferred form, have signal generating elements whereby the speed of rotation of the drum unit is controlled to prevent sag in the run of the strip material.
