  • Patent number: 6955533
    Abstract: An apparatus for extending food dough is provided that is compact and has a relatively long conveying path for food dough that extends the food dough. Also, the apparatus can be easily cleaned and maintained. It includes a lower frame (3) having a food-conveying member to convey food dough in one direction, an upper frame (5) located above the lower frame, and a cluster of a plurality of extending rollers that are located within the upper frame. To extend the food dough the extending rollers are arranged to be endless and rotatable. The upper frame (5) can be moved up and down in relation to the lower frame (3) so that the cluster of the plurality of the extending rollers can be completely separated from the food-conveying member. Thus, the food-conveying member can be easily cleaned.

  • Patent number: 6939503
    Abstract: A method and an apparatus for the manufacture of pipes of thermoplastics with transverse profile features comprises mold segment halves which are circulated by twos on a molding path. A conveying device of the type of a gantry crane is provided for recirculation of the mold segment halves. On a conveying bridge that bridges the molding path, provision is made for two conveying carriages, which are movable in opposite directions and cross-wise of the direction of production and which have mounted on them a downward conveying arm with a holding device for a respective mold segment half. Provided downstream of the downstream end of the molding path are parking positions for additional mold segment halves, those of which that are closest to the molding path being carriages which are movable out of the path of displacement of the conveying arms.

  • Patent number: 6851941
    Abstract: An improved apparatus for curing fibrous insulation material includes an oven, and a lower conveyor mounted to travel through the oven. The lower conveyor includes a plurality of flights having a support surface for supporting fibrous insulation material. An upper conveyor is mounted to travel through the oven and has a plurality of flights opposite the flights of the lower conveyor. Each flight of the upper conveyor includes a support surface. The upper and lower conveyors are arranged to press the fibrous insulation material between the respective support surfaces as the conveyors carry the fibrous insulation material through the oven. A plurality of molding members are configured to mold a shape into a surface of the fibrous insulation material, and are releasably retained on the flights by a plurality of retaining members. The retaining members are automatically releasable when the flights are moving, such that the releasing of the retaining members unlocks the molding members from the flights.

  • Patent number: 6827566
    Abstract: A blade for use in a tire mold, a combination of the blade with the tire mold, and a method of attaching the blade to the tire mold. An edge portion of the blade is received in a slot in the tire mold, and a body portion extends therefrom to form a sipe in a tire. One or a pair of tab portions attached to the edge portion is received in an indent in the slot, and a wedge forces the tab portion or portions into a locked position as the blade is driven into the slot. A break-away tendon or tendons attach the wedge to the tab portion or portions and break to allow wedge movement for achieving the locked position when the blade is driven into the slot. Alternatively, a wedge is pre-positioned in an housing in the indent whereby blade tab portions move into a locked position upon contact with the wedge. The mold is engraved, and the blade is formed by laser or water jet cutting.
