Abstract: A positioning apparatus operates to advance and rotationally orient a container during packaging of a product and broadly comprises a conveyor, a rotor assembly mounted to the conveyor, a rotary drive means and orientation sensing means. The rotor assembly includes a holder adapted to receive a container in a supported state with the supported container being aligned along the rotor axis such that the container may be rotated thereabout. The rotary drive means operates to selectively engage the rotor assembly and the supported container for rotatably orienting the supported container with respect to the rotor axis. The orientation sensing means monitors rotational orientation of the supported container, and the conveyor operates to advance the rotor assembly and the supported container during the packaging of the product.

Abstract: An apparatus dispenses flowable material from a source and includes a dispensing nozzle that reciprocates along an axis. A metering assembly includes a metering cylinder, a metering element reciprocally movable in the interior of the metering cylinder and a switching valve to switch the metering assembly between a metering mode wherein material flows into the metering cylinder and thereby displaces the metering element and a discharge mode. A metering element drive moves the metering element into the metering cylinder during the discharge mode to displace material thereby to dispense material through dispensing nozzle. A lift bracket is mounted for common equidistant movement with the metering element, and the dispensing nozzle is interconnected to the lift bracket for equidistant movement in one direction.

Abstract: Disclosed herein is a method and apparatus for forming a sheet of extruded deformable polymer with a plurality of longitudinally extending fracture lines along which splitting can occur to sub-divide the sheet into a plurality of filaments or tapes. The apparatus includes an elongated embossing roll having circumferential ridges formed on the periphery thereof with a cooperable backing roll positioned to press the sheet into engagement with the embossing roll so that the ridges and intervening grooves of the embossing roll are formed in the hot plastic sheet. The zone between the backing roll and embossing roll constitutes a first nip zone. A pressure roll is disposed adjacent to the embossing roll with a second nip zone being defined between these two rolls.
