A cutting tool for cutting materials with a straight perpendicular cut, an angled cut, a length-wise cut, and/or a notched cut. The cutting tool including a base, a pair of supports, a cam pivotally connected to the pair of supports, and a blade holder and a blade positioned between the cam and the base, where the blade holder and the blade are slideable from a first cutting position to a second cutting position for cutting notches and other shapes into the flooring materials.

A dispenser for sheet material may include a feed roller with an integrated cutting mechanism that is movable with the feed roller for at least partially cutting or perforating the sheet material during dispensing thereof.

A punch apparatus includes a drive unit and a driving force transmission mechanism that transmits a driving force output by the drive unit to a rod. In the driving force transmission mechanism, a cam groove is formed in a cam block connected to a piston rod, and a rotating roller, which is pivotally supported on a displacement body connected to the rod, is inserted through the cam groove. The cam groove has a first groove portion and a second groove portion, which are inclined at predetermined angles of inclination with respect to the displacement direction of the cam block. When the rod is made to descend toward the workpiece, the rotating roller moves from the second groove portion into the first groove portion, which has a small angle of inclination, whereby the driving force transmitted to the rod is boosted.

Cutting tools for pipe cutting frames are disclosed. Example split frame pipe cutting tools include a frame and a slide tool configured to position a cutting edge in contact with the workpiece, the slide tool comprising: a radial advancement mechanism configured to provide radial advancement of the cutting edge based on circumferential advancement of the slide tool by the frame; and an axial guide rail; a recirculating bearing carriage configured to slide in an axial direction along the axial guide rail and to couple the cutting edge to the axial guide rail; an axial advancement mechanism configured to advance the cutting edge in the axial direction with respect to the workpiece by translating radial advancement by the radial advancement mechanism to axial advancement based on a cutting template coupled to the radial advancement mechanism.

A cutter can move a movable knife by two cutter drive gears without the movable knife becoming skewed. The cutter 10 of a mobile printer 1 has a fixed knife 11, and a cutter drive mechanism 32 that moves the movable knife 31 straight to and away from the fixed knife 11. The cutter drive mechanism 32 has two cutter drive gears 51 that are driven synchronously, and a cutter drive plate 54 disposed between the two cutter drive gears 51 and the movable knife 31. The two cutter drive gears 51 cause the cutter drive plate 54 to move to and away from the movable knife 31 on a longitudinal axis Y (direction of travel), thereby moving the movable knife 31 to and away from the cutter drive plate 54. If the cutter drive plate 54 becomes skewed when the two cutter drive gears 51 move the cutter drive plate 54, the guide mechanism 81 prevents skewing of the movable knife 31.

System and methods for performing a full cut and a partial cut of paper are disclosed herein. According to an aspect, a system comprises a paper cutter system comprising a motor operable to move in either a first direction or a second direction. The paper cutter system also comprises a movable blade. The paper cutter system also comprises a cutter mechanism configured to move the blade to perform a full cut of paper when the motor moves in the first direction and move the blade to perform a partial cut of paper when the motor moves in the second direction.

The present disclosure is directed, in part, to a cutting apparatus comprising a drive shaft having a longitudinal axis, a drum configured to orbit the longitudinal axis when driven by the drive shaft, a first actuator, and a cutting assembly joined to the drum and configured to orbit the longitudinal axis with the drum. The cutting assembly comprises a second actuator operably engaged with a portion of the cutting assembly, and a cutting device driven by the second actuator. The second actuator is configured to rotate the cutting device at least 1,500 revolutions per minute during cutting of an article. The first actuator is operably engaged with a portion of the cutting assembly and is configured to reciprocate the cutting device in directions substantially parallel to the longitudinal axis as the cutting assembly orbits the longitudinal axis.
