Patent number: 4281500Abstract: Cylindrical rolls of paper (1, 96, 315) are completely enclosed with wrapping material (105) by simultaneously rotating the roll about its longitudinal axis and rotating the roll end-for-end. A turntable (35, 200) may be used to rotate the roll end-for-end, and a drive roll (65, 265) carried by the turntable is driven to rotate the roll about its longitudinal axis during rotation of the turntable.Type: GrantFiled: July 13, 1979Date of Patent: August 4, 1981Assignee: Wisconsin Tissue Mills Inc.Inventors: George P. Mueller, Urban A. Urban, Kermit J. Muenster, Donald A. Ludwig

Patent number: 4232501Abstract: An apparatus and process for automatically wrapping packages with a full-web or spiral overwrap. The apparatus includes a film handling assembly in which stretched film is wrapped around the load rotated by a turntable. When the load is stopped in a home position a cutting and sealing assembly is transported into the film path, engaging the film and displacing it out of its original dispensed path. Rotatable clamps mounted on the turntable are rotated upward to grab the lower portion of the stretched film web while the sealing mechanism of the assembly engages the trailing edge of the film web to hold it against the film wrap, after which a cutter blade of the assembly is extended into the film web, severing the film web so that the load can be transported off the conveyor with the sealing mechanism pressing the trailing edge of the film onto the package wrap.Type: GrantFiled: May 1, 1978Date of Patent: November 11, 1980Assignee: Lantech Inc.Inventor: William H. Stackhouse

Patent number: 4189894Abstract: Method of and means for wrapping generally cylindrical products with plastic film in which the film extends from a supply roll over a supporting means and terminates in a free end. The product is placed on the supporting means, the free end of the film is transferred to the product and the product is rotated to draw film from the supply roll and cause it to be wrapped around the product. The wrapped product is removed from the supporting means and the film is severed.Type: GrantFiled: August 28, 1978Date of Patent: February 26, 1980Assignee: Curtis & Marble Machine CompanyInventor: Robert Laing

Patent number: 4152879Abstract: An improvement is disclosed in wrapping apparatus for palletized loads of the kind having a rotatable platform where the load is received, and a roll of plastic film mounted adjacent to the platform for vertical movement so that plastic film can be dispensed onto the load while the platform rotates, in order to enwrap the load helically. The improvement is the provision of an elongated roller member pivoted adjacent one of its ends to the platform so that is can swing between two positions through an arc in a vertical plane. In the first position the member bears against a frictional surface on the platform, and in the second position it is spaced from the frictional surface. In swinging from the second to the first position at the end of a wrapping operation, the elongated roller member catches the film and pinches it between itself and the frictional surface.Type: GrantFiled: June 21, 1977Date of Patent: May 8, 1979Inventor: Michael H. Shulman
