This divisional patent is directed to the feature whereby the paper is pushed towards the rotor by means of a drive roller located closely adjacent the platen, at a location in which the paper is curved to form an arc. The drive roller is much narrower than the width of the paper, and the stiffness of the paper column which the roller pushes is relatively great. The curved exterior of the housing is used both as a housing and as a curved paper guide. A hinged guide co-acts with the housing in guiding the paper and forming it into an arc.Type: GrantFiled: March 22, 1978Date of Patent: December 11, 1979Assignee: SCI Systems, Inc.Inventor: Olin B.

Patent number: 4096538Abstract: In a magnetic tape cassette, closely spaced support pins for guiding and holding a magnetic recording tape in contact with a recording and reproducing head are provided with a V-shaped concave guide surface. The V-shaped guide surface of each support pin bends the tape along its transverse axis when the head is inserted into the cassette and the tape is pressed thereon, thereby aligning the center of the tape with the center of the guide surface so that the tape is always maintained in a predetermined position with respect to the magnetic head, at the same time increasing the stiffness of the tape portion between the pins. The pins at their rear face also support a spring plate having a pad to contact the tape.Type: GrantFiled: May 12, 1977Date of Patent: June 20, 1978Assignee: Fuji Photo Film Co., Ltd.Inventor: Kengo Oishi

Patent number: 4094451Abstract: A ticket dispenser automatically advances a continuous web of lottery tickets, one ticket length, halts the advance, and severs the end most ticket to drop into a delivery chute upon actuation. The dispenser is capable of handling ticket webs which are difficult to tear or have poor perforations, by pre-breaking the web along its transverse lines of perforation, in opposite angular directions by means of a set of three cylindrical rolls, and by moving a breaker bar upwardly into a slot between an inclined bed plate and a horizontal bed plate to slice each successive, prebroken perforated line. The printed indicia can thus be on the upper surface of the web and the tickets delivered face-up.Type: GrantFiled: November 4, 1976Date of Patent: June 13, 1978Assignee: Granite State Machine Co., Inc.Inventor: George F. Wescoat

Patent number: 4072554Abstract: A portable paper hole punch and hole reinforcement tape applicator comprising a housing including operating mechanism for feeding a pressure sensitive tape over a sheet of paper. Punch means and a pressure pad are provided for punching a hole through the tape and paper and applying pressure to seal or bond the tape to the paper. Tape feed means are provided and include means for imparting a transverse curl to the tape so that the latter is stiffened lengthwise to prevent bunching or jamming during the hole punching operation.The surfaces of all parts of the device contacted by the adhesive side of the tape are coated with "Teflon" or other suitable material, so that the tape will not adhere thereto as it is moved thereover.Type: GrantFiled: April 5, 1976Date of Patent: February 7, 1978Inventor: John D. McKibben

Patent number: 4011977Abstract: An applicating machine for applying short lengths of flexible fibrous material having an adhesive coating to a surface. The applicator uses a pair of fingers to hold the fibrous material onto the surface of an applicating pad and a rod to strip the material from the fingers. The fingers are initially spaced from the pad to permit a measured length of flexible material to be moved between the pad and the fingers. The fingers are then retracted to a closed holding position. The fingers support the length of material during the severing of a short length of material by cutting means and while the applicating pad transports the severed strip to the surface for application. The measured length of the flexible material to be dispensed and applied, the applicating pad, and the fingers are moved downward the severed length of fibrous material being applied to a product.Type: GrantFiled: September 25, 1975Date of Patent: March 15, 1977Assignee: Minnesota Mining and Manufacturing CompanyInventors: Larry A. Bettenhausen, James H. Casey, Robert A. Luhman

Patent number: RE35844Abstract: A trough structure is provided for bending a web of paper widthwise to provide beam strength and controllability to the web of paper, for aiding in guiding the web of paper in a straight path. The trough structure causes the paper to curl widthwise to conform with the shape of the trough structure. The trough structure comprises a concave or convex lower wall upon which the paper flows, open ends through which the paper flows, and shoulders which attach to both sides of the lower wall and extend substantially horizontally from the sides of the lower wall to symmetrical positions above the lower wall. The shoulders act to contain the paper in the trough structure and guide the paper through the trough structure. A drive roll is provided for driving the paper through the trough structure. No buckling of the paper is caused when any slight misalignment occurs between the paper and the drive roll, and this slight misalignment is self-correcting due to the edge guiding function of the trough structure.Type: GrantFiled: May 24, 1995Date of Patent: July 14, 1998Assignee: Roll Systems, Inc.Inventor: H.
