Patent number: 5957025Abstract: The present invention provides a bale slicer that processes large forage bales into a form useable by TMR mixing systems. The bale slicer is simple to operate, reduces the power required to process a bale as compared to other bale processors and processes forage bales into a size suitable for use as feed. The bale slicer includes a main frame, bale chamber, platforms, a cutting mechanism, and power mechanism. The bale slicer utilizes a slicing motion by the cutting mechanism to process the large forage bales. The forage bale to be processed remains stationary and is held in its compressed form by the bale chamber during slicing. The cutting mechanism passes by the bale chamber in order to slice the bale. At the end of each slice made by the cutting mechanism, the forage falls to the floor and the bale drops down in the bale chamber in preparation for the return pass by the cutting mechanism. The fallen forage is then ready to be transported to a TMR mixer.Type: GrantFiled: October 31, 1996Date of Patent: September 28, 1999Assignee: The Penn State Research FoundationInventors: Dennis R. Buckmaster, Kevin M. Smith

Patent number: 5904283Abstract: A note paper sheet dispenser adapted to supply a user with a note paper sheet whose dimensions are determined by the user. The dispenser includes a rectangular base above whose rear end is mounted for rotation a strip paper roll in which the underside of the paper strip is coated with a longitudinal band of low-tack pressure-sensitive adhesive. Mounted above the base is an endless conveyer belt which runs between a motor-driven roller adjacent the paper roll and an idler roller adjacent the front end of the base. When the motor is energized, the belt then draws paper strip from the roll along the belt to a length depending on the time period during which the motor is energized. A tear-off blade above the belt and adjacent the roll permits the length of paper strip lying in the belt to be torn off to provide a note paper sheet of the desired length that can be written on and then temporarily adhered to a document or other object.Type: GrantFiled: May 10, 1996Date of Patent: May 18, 1999Inventor: Maurice S.

Patent number: 5901626Abstract: An apparatus for severing fiber bale ties and removing cut ties from a fiber bale includes a tie cutter for severing a metal tie surrounding the bale at a bale location; and a first metal sensor for responding to a presence of a metal tie around the bale. The first metal sensor is situated ahead of the tie cutter, whereby the first metal sensor passes by the bale tie prior to being severed by the tie cutter. There is further provided a second metal sensor for responding to a presence of a metal tie in engagement with the bale. The second metal sensor is situated after the tie cutter, whereby the second metal sensor trails the tie cutter relative to the fiber bale. The apparatus further has a device for displacing the bale and the first and second metal sensors relative to one another.Type: GrantFiled: June 3, 1996Date of Patent: May 11, 1999Assignee: Trutzschler GmbH & Co.

Patent number: 5899128Abstract: A continuous web of sheet material is fed through the lip of a first pair of driven pull rolls around a series of idler rollers and through the nip of a second pair of driven pull rolls. The pairs of pull rolls are selectively rotated to exert a desired tension on the web in a tension zone formed between the pairs of rolls. One pair of pull rolls operates as feed rolls to advance a preselected length of the web to a rotating cutter mechanism so that envelope blanks of a selected length are cut from the web for each revolution of the cutter mechanism. The feed rolls are operated by a servo-controlled motor responsive to an operator initiated signal to adjust the feed length without interrupting the feed of the web to the cutter mechanism. The second pair of pull rolls operates as tension rolls and is servo-motor controlled to maintain a preselected tension on the web fed to the cutter mechanism.Type: GrantFiled: June 13, 1997Date of Patent: May 4, 1999Assignee: F. L. Smithe Machine Company, Inc.Inventors: Eliot S. Smithe, Michael P. Lambert, Jason H. Wilkinson

Patent number: 5873291Abstract: Apparatus for cutting fibrous reinforcement material in relationship with an ejector nozzle. The apparatus comprises at least two feeding rollers and a rotary cutter which is provided with a substantially cylindrical mantle surface with attachments for a number of knives. These cooperate with a support roller with an elastic surface layer for forming a thread nip. The mantle surface of the cutter is provided with slot-shaped recesses for the fiber thread, which recesses extend peripherally along the mantle surface and between successive knives. The recesses enable the thread to be fed forward by means of the feeding rollers at a feeding rate which deviates from the speed of the cutter, for adaptation of the cutting length of the fiber thread.Type: GrantFiled: January 21, 1997Date of Patent: February 23, 1999Assignee: Aplicator System ABInventor: Kjell Sand
