Abstract: 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.

Abstract: 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.

Abstract: A method for manufacturing a rotary cutting tool for fabricating a sheet having transverse slits. The rotary cutting tool has a cylindrical body having generally longitudinally extending grooves, and cutting blades. The cutting blades are first fitted in the grooves with the cutting edges seated on the bottom surfaces of the grooves, and the base surfaces of the cutting blades projecting from the grooves are machined with a rotary grinding wheel while the cylindrical body is rotated. The cutting blades are then removed from the grooves and are finally fitted in the same grooves. The cutting edges of the cutting blades can be accurately arranged about an axis of the cylindrical body, and the rotary cutting tool can be easily manufactured.

Abstract: 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.

Abstract: 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.
