  • Patent number: 5018339
    Abstract: An apparatus for shrinking a wrapping about goods carried on a pallet has a transport device defining a support surface for displacing the palletized goods in a transport direction and including an upstream conveyor, a station conveyor spaced downstream by an upstream gap from the upstream conveyor, and a downstream conveyor spaced downstream by a downstream gap from the station conveyor. A heat ring has upstream and downstream portions and side portions extending in the direction therebetween. This ring is displaceable between a lower position with the upstream and downstream portions in the gaps below the surface and the side portions flanking the station conveyor and an upper position above the surface. An actuator displaces the ring between its upper and lower positions.

  • Patent number: 4438786
    Abstract: A knife construction for a double-lift open-shed Jacquard loom includes two knife boxes which are movable in opposite directions past each other. The knives of each knife box consist of a carrier member having hook plates fastened thereto and provided with spaced control hooks. Lifter members formed as flat bars controlled by main needles arranged transverse to the knives each include two main noses engageable with the control hooks of the movable knives and a holding-up nose engageable with a stationary upper-shed knife. The formation of the control hooks and the main noses in the control direction of the main needles permits movement of the lifters intermediate the control hooks of a knife.
