A hole puncher is provided, including: a frame, including a base and a guide portion, the base including at least one punching hole, the guide portion including at least one guide hole corresponding to the at least one punching hole, there being a distance between the punching hole and the guide hole; an operating lever, provably connected to the frame; at least one punching rod, driven by the operating lever, being relatively movable within the at least one guide hole and movable to come within or out from the at least one punching hole, each punching rod including a first straight section, a second straight section and a tapered section which is tapered from the first straight section toward the second straight section.

A food slicer assembly includes a housing defining a first opening and a second opening perpendicularly arranged. A slicing blade received at the second opening enters the first opening of the housing. A coupling releasably couples a food product or a food product packaging to the housing. The first opening receives a food product therethrough, the second opening receives the slicing blade therethrough, and the slicing blade slices the food product arranged in the first opening such that the food product is divided into multiple portions using the food slicer assembly. The slicing blade may pass into the first opening from a first end, and upon reaching the second end, the slicing blade seals the food slicer assembly at the first opening. The assembly may be a cheese slicer assembly for slicing a block of cheese so that a slice of cheese can be removed from the first opening.

A mechanism is described herein to drive slitter and cutter waste in a direction that allows for a more advantageous use of the waste collection bin's volume. The waste drive mechanism allows for at least one armature that drives the waste in a desired direction. The armature is made from a material that is flexible, with a curved shape to allow a pre-loaded force against a contact surface of the waste collection bin. The pre-loaded flexible armature against a contact surface of the collection bin provides sufficient force to drive the waste it in a desired direction, allowing for a more consistent use of the waste collection bin spatial volume.

Devices and methods are provided for cutting or forming tapered surfaces on the end portions of tube or pipe lengths prior to forming joints in adjoining lengths. A device body includes multiple guide surfaces, each having distinct size and shape to engage with an open end of a one of a multiple of tube of predetermined diameters. In intended use, a powered cutting device is rotated about the end of stationary tube or pipe.

In a method for guiding a cutting head in relation to a material, a position and a speed of the cutting head are set by means of a drive unit depending on a desired position value and a desired speed value established by an interpolator unit, a control signal for the drive unit is determined, a distance between the cutting head and the material is determined with a distance sensor, and a corresponding distance signal is provided. The distance signal is compared with a predetermined comparison distance to yield a distance-control signal, and the control signal for the drive unit is additionally determined dependent upon a distance-control signal. The comparison distance is subtracted from the distance signal and the difference is superimposed on the actual position signal, which is delayed by a first time period, wherefrom the distance-control signal is determined.

The invention relates to a cutting device and a method for cutting paper, wherein the cutting device comprises a cutting blade and a counter-member that cooperate to cut the paper along a cutting line, wherein the cutting blade is movable towards and away from the counter-member in a driving direction transverse or perpendicular to the cutting line, wherein the cutting device is provided with a drive mechanism to drive the movement of the cutting blade with respect to the counter-member in the driving direction, wherein the drive mechanism comprises a first spindle and a second spindle, wherein the drive mechanism further comprises one or more motors and a mechanical synchronization element in the form of a chain or a toothed belt that is arranged to synchronize the first spindle and the second spindle in a 1:1 ratio.

A fixture includes a pipe having a vertical axis that is coaxial with a center of the pipe, a cutting element having a cutting blade, and a jig assembly coupled to the cutting element and arranged to orient the cutting blade at an angular orientation relative to the vertical axis of the pipe. Related methods and components are also provided.

A cutting device and a method for cutting paper are provided. The cutting device includes a cutting blade and a counter-member. The cutting device is further provided with a first guide and a second guide extending in or parallel to the driving direction for linearly guiding a holder that holds the cutting blade. Each of the guides includes a guide body. The guide bodies of the first guide and the second guide, when released, are arranged to be rotatable relative to the frame about a first adjustment axis and a second adjustment axis, respectively. Each guide body includes an eccentric section that moves eccentrically about the respective adjustment axis and that is arranged to convert the rotational movement of the guides about the respective adjustment axes into a linear movement of the holder in the adjustment direction.
