  • Patent number: 5105602
    Abstract: An automatic wrapping apparatus of cylindrical articles, particularly plastic bobbins. The apparatus includes feed rollers for feeding two wrapping sheets therebetween in opposed manner to form a bottom portion for a wrapping bag. A loading device is provided for loading bobbins onto the bottom portion by holding each unit of regularly arranged bobbins and dropping it in an orderly state. A support member is provided for supporting the bobbins unit by unit from underneath and causing the bobbin unit whenever dropped to descend by the bobin height, thus stacking bobbin units one upon another. A basket-like retainer is provided for receiving the bobbin units descending with stacking to retain them in the place so as to keep the orderly state. A heat sealer is provided for uniting the bottom portion and a top margin of the wrapping bag. A side heat sealer is provided for uniting both sides of the bag.

  • Patent number: 5103617
    Abstract: Method and apparatus for wrapping a signature bundle by moving a wrapping sheet into the path of movement of a bundle, said sheet being maintained in self-supporting fashion by imparting a bend thereto as it is fed to the wrapping station. The bundle "crashes" into the sheet causing it to collapse and wrap itself about the bundle. When the wrapping operation is completed, the wrapping sheet is wrapped around three contiguous surfaces of the bundle. The sheet is automatically cut and a new wrapping operation is initiated. The wrapping sheet may be printed upon by an ink jet printing characters "on the fly". The characters are printed backwards and "bleed through" the wrapping sheet to appear in normal manner.

  • Patent number: 5103529
    Abstract: A structure is provided to retain in an axial direction a support bearing inserted into a receiving lug of a vehicle part. Such support bearings have a rubber bush which projects with its endpieces out of the receiving lug, possesses a bearing core and is supported on one side of the receiving lug by means of a flange of a sheet-metal casing. An annular-bead-like bush endpiece facing away from the flange engages over an edge on the other side of the receiving lug. The retention structure can be in the form of a circumferential groove in the annular-bead-like bush endpiece, into which, after the support bearing has been introduced into the receiving lug, a spring ring can be inserted a spring ring which, in the inwardly spread state, has a diameter larger than the inside diameter of the receiving lug. The spring ring thus prevents axial shifting of the support bearing in a direction in which the bead-like bush endpiece would be drawn into the receiving lug.

  • Patent number: 5103528
    Abstract: A refrigration, foam sealing bushing is provided for use within a refrigeration door cavity. The bushing is formed of a male member, and a female member. The male member includes a head portion, an upper shank portion, a reduced lower shank portion, and a disc-like member. The female member is formed of a tubular section having an open upper end and an open lower end. The tubular section has an axially extending bore which extends between the open upper end and the open lower end for telescopingly receiving the lower shank portion of the male member. Passageways are formed between the outer surface of the reduced lower shank portion and inner surface of the axially extending bore of the tubular section for permitting air to escape from the door cavity but yet preventing foam insulation from escaping during the injection of the foam insulation into the door cavity.

  • Patent number: 5093958
    Abstract: To prevent an automobile mat from moving forward, a strap with a metal or plastic loop at the end is attached to the rear underside of a floor mat. In front of the automobile seat one side of an elongated "S"-shaped clip is forced over the exposed edge of the automobile's original carpeting. The other side of the clip is then in an upward direction with the open end of the clip facing toward the rear of the automobile. The loop attached to the floor mat is inserted intothe upward facing portion of the "S" clip. The length of the strap attached to the loop is sized to allow hand space to reach under the floor mat during the attaching process. The "S" clip is made of a spring-type material, shaped to tightly squeeze over and be tightly held by the thickness of the automobile carpeting. The shape of the clip also prevents the unintentional separation of the loop from the clip.
