Abstract: The bagging machine has a rotary table with openings to receive a series of bags. Each bag is staked onto four pins two of which are stationary and two of which are laterally movable. After filling, the bag is heat sealed using a pair of heat seal bars and then severed by a fly knife above the heat seal. The bag is then removed manually or automatically.

Abstract: The bag filling and forming machine employs a chute for conveying a flow of loose fill material, a form for enveloping a sheet of plastic film about the chute, a heat-seal roller for sealing the overlapped edges of the film to form a tube and heat-seal bars for sealing the tube at spaced apart positions to form the top and bottom of bags. A pair of conveyors are provided for continuously moving the formed tube relative to the chute and fingers are provided for spreading the tube into a flattened configuration for heat-sealing purposes. A hot wire or cutting knife is provided for cutting off a filled bag after heat-sealing.

Abstract: The perforating machine is provided with a perforating roll having a perforating bar and a base roll below the perforating roll which can be moved between a raised position and a retracted position. In the raised position, the base roll allows the perforating bar to perforate a web passing between the two rolls. In the retracted position, the base roll lowers the web away from the perforator roll so that a perforation is not effected. A programmer is also provided to program the motion of the base roll so as to adjust the centerline to centerline spacing of the lines of perforations in the web. The perforator roll is also driven by a transmission employing elliptical gears so that the perforator roll is accelerated prior to perforating the web and decelerated thereafter. The machine may also be used to cut the web into a series of panels rather than simply perforating the web.

Abstract: The pool cover is made of multi-layer light weight construction having a translucent top layer to permit sunlight to pass through an opaque bottom layer for absorbing sunlight passing through the transparent layer. In addition, a plurality of pockets are formed in the opaque layer having air encapsulated therein. When in use, the opaque layer becomes heated by sunlight thereby transferring heat by contact to the body of the water in the pool while also blocking light from the body of water to inhibit algae growth. The heated trapped air also serves to conduct heat to the body of water while also acting as a thermal insulation barrier during non-daylight hours. The pool cover may also be turned upside down in use. In other embodiment, all layers may be opaque.

Abstract: A filling machine employs a rotary table with a plurality of peripheral openings for receiving bags for filling with particulate matter as the table rotates. A gathering and severing unit is provided on the table in order to close the bag after filling. This unit includes a pair of guide plates which serve to gather a part of the bag when the guide plates are moved towards each other. In addition, a reciprocally mounted severing blade is positioned on one of the guide plates and is reciprocated transversely of the movement of the guide plates in order to sever the gathered part of the bag. The blade may be reciprocated twice to ensure complete severance of the gathered part of the bag.

Abstract: The insulation barrier is made with a flexible foam polyethylene substrate and a film which is secured to at least one side of the substrate and which extends from at least one lateral edge of the substrate. The insulation barrier may be supplied in roll form or in panel form. In one embodiment, the film may be provided with a plurality of small holes to permit moisture vapor to pass through under a differential pressure on opposite sides of the barrier. In still another embodiment, the substrate may be provided with spaced apart embossments while the film is provided with pockets receiving the embossments. The barrier has multiple uses as an insulation/vapor barrier for interior and exterior use on buildings including use in roofing, flooring and walls.

Abstract: A filling machine includes a rotary table having a plurality of peripheral openings each of which is provided with upstanding posts for staking of a bag thereon for suspension through the opening. A blower is provided at a second station for blowing air into the bag to open the bag. A chute is provided for delivering material into the open bag. A gathering and severing unit is provided to close and staple the bag in a closed position.

Abstract: A laminated bubble wrap packaging material is provided with has a tackifier, such as a polybutene, dispersed homogeneously throughout the packaging material. The packaging material is adherent to itself as well as and does not leave a residue. The tackifier is incorporated into the plastic material during extruding of the layers of plastic material into thin plastic films.

Abstract: The pool cover is made of multi-layer light weight construction having transparent top layers to permit sunlight to pass through, an opaque layer for absorbing sunlight passing through the transparent layers and a reflective layer to transfer heat from the opaque layer into a pool of water. In addition, a plurality of pockets are formed on one of the transparent layers to encapsulate air therein. In one embodiment, the opaque and reflective layers may be incorporated into a single layer with an opaque surface on one side and reflective surface on the other side. Also, the edges of the cover may be sealed so that the entire cover has an encapsulated air layer. The cover can be reversed to place the reflective layer topmost so as to reflect sunlight from the pool, e.g. for short term pool closure. The opaque layer and reflective layer reduce sunlight penetration and thus inhibit algae growth while the insulating layer reduces heat movement either in or out of the water.

Abstract: The process of making a fire-retardant insulation barrier provides a single step of applying an emulsion comprised of aluminum trihyridate and polyvinylchloride to one side of a foamed molded or extruded or fabricated polystyrene board. After the emulsion dries to a coating, the board can be shipped. The aluminum trihydrate and polyvinylchloride are in a ratio of approximately 4 to 1 to 1 to 4 and the emulsion is applied at a wet weight of 1 to 6 pounds per 32 square feet of board area.

Abstract: An extrusion die having a die face with plural apertures therethrough, the die face having a contour such as to mate with a non-linear cutting edge of a rotary cutter mounted for rotation about an axis parallel to the die face.

Abstract: The packing elements are each formed with a hooked configuration so as to abut each other without interlocking with each other. The free ends of the two legs of each element project beyond the main body portions so as to impart a hooked effect to the elements. The elements can be poured from a hopper into a container.

Abstract: A plastified mass of thermoplastic material containing an expanding agent is extruded and sliced into pieces by shaped cutting edges to produce--on expanding--elements which are shaped in a billowed manner or a double-bubble manner. The billowed elements have an inturned peripheral edge which prevents nesting and interlocking together when used in a shipping container. Similarly, the double bubble elements preclude nesting and interlocking.

Abstract: The steam expander conveys the expanding heat expandable thermoplastic elements along a horizontal axis using a plurality of paddle frames. The paddle frames serve to agitate and tumble the elements during movement from an inlet to an outlet. At the same time, steam is injected into the housing of the expander to expand the elements. The expanded elements can be drawn off via a vacuum line to an overhead hopper or hoppers.
