Patent number: 5320267Abstract: A web transport apparatus that will not cause the web to break by exerting external forces in different ways on two lateral sides. The transport apparatus includes a group of pins that are studded on flat plates connected together to form a chain on either side of a web so that it is transported in multiple stages as it is retained on two lateral sides. An annular member supports the web from the inside by pins in each of the reversing sections that rotate to reverse the direction of web transport, with the piercing end of each pin facing either inward or outward. The annular member has a central shaft located at the center of the locus of rotation of the flat plates and has an outside diameter substantially equal to the diameter of the locus of rotation of the web. Preferably, the annular members rotate at the same speed as the web.Type: GrantFiled: October 30, 1990Date of Patent: June 14, 1994Assignee: Fuji Photo Film Co., Ltd.Inventors: Seiichi Oono, Hiroshi Nakajima, Masayuki Kawarada, Hiroki Saito

Patent number: 4921517Abstract: Glass fibers are projected along an oscillating trajectory onto a travelling conveyer to form a glass fiber mat. The trajectory is made to oscillate by stripping glass fibers from a pulling wheel by means of a stripping edge, such as a tight wire, which is oscillated arcuately immediately adjacent the surface of the pulling wheel. The stripping means is oscillated at a greater angular velocity where the trajectory makes a greater angle with the conveye=r in order that the impingement point of the trajectory upon the conveyer travel at a substantially uniform velocity across the conveyer so that a mat of uniform density is fabricated.Type: GrantFiled: February 13, 1989Date of Patent: May 1, 1990Assignee: Superior Glass Fibers, Inc.Inventor: Steven A. Sholl

Patent number: 4570916Abstract: An apparatus and method are provided whereby two superposed strips (26, 28) of documents are conveyed in a direction of conveyance (30) toward a downstream workstation. The strips (26, 28) are conveyed over one another in a direction of superposition whereby leading edges of documents of one strip alternate in sequence in the direction of conveyance (30) with the leading edges of documents in the other strip. A determination and control circuit (190) is provided to determine whether the leading edges of documents in one strip are tending to creep up on the leading edges of documents in the other strip due to differing speeds of motion of the two superposed strips. If a creeping condition is determined by the circuit (190), the circuit (190) energizes braking means (400) whereby the motion of at least one of the strips is at least temporarily retarded for rectifying the creeping condition.Type: GrantFiled: November 14, 1984Date of Patent: February 18, 1986Assignee: Bell & Howell CompanyInventor: Callie R.

Patent number: 4315789Abstract: A fiber glass mat making process is described which utilizes an improved method of transferring unbonded mat from a mat forming chain to a bonding station on a continuous basis.The system involves passing the unbonded mat from a continuous conveyor surface to a roll which has on its surface a draped conveyor chain rotating around the roll but driven by the roll on which it is draped. By permitting the draped chain to hang freely below the roll and to rotate with the roll stray strands falling between the conveyor surface and the roll are returned on the draped chain to the feed end of the bonding station. Means are also provided to maintain the draped chain centered to insure that mat is delivered to the bonding station in a straight line from the conveyor surface.Type: GrantFiled: June 13, 1980Date of Patent: February 16, 1982Assignee: PPG Industries, Inc.Inventor: Richard R.

Patent number: 4183751Abstract: A process for developing a photosensitive material, and a device therefor, are disclosed wherein an image on a photosensitive material consisting of a cover base laminated through the intermediary of a photosensitive layer to a support member is developed into a visible image by stripping the cover base from the support member. A preliminary stripping step of stripping the cover base from the support member in the leading end portion thereof is first performed. This is immediately followed by the reorientation of the leading end portion of the cover base to bring the same into registration with the support member. Therefore, a final stripping step is performed wherein the cover base is successively separated from the leading end portion thereof towards the trailing end thereof from the support member.Type: GrantFiled: November 22, 1977Date of Patent: January 15, 1980Assignee: Fuji Photo Film Co., Ltd.Inventors: Nobuo Matsumoto, Osami Tsuji, Shinji Hamada

Patent number: 4028779Abstract: The present disclosure relates to a size reduction apparatus such as a granulator and particularly to a novel feed assembly for such a granulator whereby thin plastic sheet material may be successfully granulated at high through-put speeds. The construction includes the use of a closed chamber mounted above the granulator chamber and having a longitudinally orientated feed slot therein, directly above which a pair of nip rolls are mounted so as to enable sheet material to be fed directly into the chamber of the granulating machine towards the rotor and in a generally radial direction thereto. The device is operated while the chamber thereof is at least partly full of partially granulated material.Type: GrantFiled: December 17, 1975Date of Patent: June 14, 1977Assignee: Leesona CorporationInventor: Sunil C.

Patent number: 4014487Abstract: An improved system for directing a web of flexible material to a predetermined location, and more particularly, a system for directing the end or tail of a moving web into threading engagement with rolls forming a nip or the like. In this system a gas such as air is directed through a restricted opening under pressure whereupon it attaches itself to a flow attachment surface due to the "Coanda effect", so that it entrains ambient air and the moving web tail. In a preferred form of the system, after the web tail has been entrained and conveyed a predetermined distance, a substantial portion of the combined flow of the entraining gas and the entrained ambient air are diverted off toward a different direction. At the location of diversion, restraining means is provided for preventing the web tail from moving with such substantial portion of combined flow.Type: GrantFiled: March 31, 1976Date of Patent: March 29, 1977Assignee: Crown Zellerbach CorporationInventors: Imants Reba, Gerald Hugh Hogland
