Abstract: An improved net cutting assembly that may be used with an agricultural baler net wrapping system. More particularly, an up-cut net knife for improved cutting of wrapping material (e.g., a net) used to wrap bales of crop material in an agricultural baler. The up-cut net knife assembly improves net cutting performance by providing an up-cut net knife that moves in the same direction as the net whereby the motion of the net helps the knife get into the cut position. Further, embodiments of the up-cut knife assembly move the up-cut knife cutting edge at substantially the same speed and in the same direction as the net to be cut. This motion of the up-cut knife allows the up-cut knife to be lifted up into the net motion using a driver and then to continue on with no relative motion—or at least minimal relative motion of the knife to the net—until the knife gets into the cut position. In the cut position, the knife stops and the net is pulled against the knife blade resulting in cutting the net.
Abstract: A device for cutting food includes a slide operable to receive a food product that is slid across the slide so as to perform a cutting procedure. A cutting blade including a cutting edge is included. A switch is included operable to switch the device from a neutral position in which the cutting edge is at least one of covered and recessed, to a cutting position in which the cutting edge is neither covered nor recessed.
Abstract: A cutter device comprising a fixed blade and a movable blade is disclosed, the movable blade being opposed to the fixed blade and adapted to be displaced in such a manner that an engaging position thereof with the fixed blade shifts continuously. The cutter device is constructed so that the movable blade can be attached to and detached from a body of the device. Thus, attachment and detachment of the movable blade can be effected without requiring any troublesome work.
Abstract: A perforator has a rotary drum. A plurality of die sets are arranged at regular intervals around a peripheral surface of the drum and circulates along with the peripheral surface. Each of the die sets has a pair of die and punch. The die is secured to a die holder which is mounted to the peripheral surface, and the punch is secured to a punch holder which is linearly movable in a direction perpendicular to the peripheral surface between a punch position where the punch is fitted in the die and a retracted position where the punch is retracted away from the die. The sheet material is brought into contact with the peripheral surface within a predetermined range, and conveyed on the peripheral surface in the same direction at the same speed as the die sets. An annular punch drive cam disposed surrounding the peripheral surface drives the punch holder to move between the punch position and the retracted position.
Abstract: A packaging machine for applying and securing a continuous web of material, especially of the heat sealable type, to containers, especially open-topped containers. The machine includes an intermittently rotatable cutter for severing the web between adjacent container supports. The cutter includes camming means adjacent each end for rotating the cutter with respect to each container support to one position in readiness for further rotation between the container supports to sever the web. Support pins for carrying the container supports may be included on at least one of the supports and conveyor chains. When on the conveyor chains, support pins need be included at only some of the chain joints. The container supports may be molded from a settable material and include a convex, upward curvature to allow proper container sealing under pressure from a web applying device.

Abstract: A packaging machine for applying and securing a continuous web of material, especially of the heat sealable type, to containers, especially open-topped containers. The machine includes an intermittently rotatable cutter for severing the web between adjacent containers as well as a conveyor allowing mounting of interchangeable container supports of different sizes which cooperate with the cutter to rotate same to sever the web. The cutter need not be adjusted or modified when the container supports are changed and automatically accommodates the different sized supports.

Abstract: Apparatus for cutting and simultaneously dispensing a web of roll material comprising a carrier for a roll of material mounted in a casing and urged against a rotatable drum which is driven in rotation by manual traction applied to a free end of the material extending from the casing. A profiled pawl is supported at one of the ends of the drum and cooperates with a shock absorber and an elastic abutment to brake the drum at the end of one revolution and hold it in readiness for a subsequent pull on the material. An eccentric lever is secured at the other end of the drum and is engaged by a spring such that in a first portion of rotation of the drum, the spring absorbs energy and after a dead point, it releases its energy to drive the drum in rotation.
