A method of cutting a polymeric tubular member and apparatus therefor is provided. The method includes moving the polymeric tubular member along a central longitudinal axis into a position to be cut. Further, providing at least one actuator with a cutting blade operably connected to the at least one actuator, with the cutting blade extending lengthwise along a cutting blade axis. Then, actuating the at least one actuator and moving the cutting blade into cutting engagement with the polymeric tubular member along a driven axis that extends in oblique relation to the cutting blade axis.

Methods, apparatus, and systems for cutting material used in fused deposition modeling systems are provided, which comprise a ribbon including one or more perforations. Material is passed through at least one perforation and movement of the ribbon cuts the material. A further embodiment comprises a disk including one or more blade structures, each forming at least one cavity. Material is passed through at least one cavity and a rotational movement of the disk cuts the material. A further embodiment comprises a slider-crank mechanism including a slider coupled to a set of parallel rails of a guide shaft. The slider moves along a length of the rails to cut the material. Yet another embodiment comprises one or more rotatable blade structures coupled to at least one rod. The rotation of the blade structures causes the blade structures to intersect and cut extruded material during each rotation.

An invention is disclosed comprising a cutting chain of links that pivot without longitudinal disarticulation, yet are connected without reliance on separate connections. Lateral dislocation of the links of the cutting chain is prevented by placement of the cutting chain in a channel, which guides the cutting chain along its operational path and provides resistance against normal load. The channel may be retractable and/or comprised of lubricious, heat absorbing materials. The blade may be flexible in order to cut a variable kerf. The invention further comprises a power train and drive train, designed to optimize the cutting chain for one of many applications.

A bread conveying apparatus includes a flight conveyer including a first flight for urging a bread, an endless revolving member on which the first flight is mounted, and a driving member and a driven member, the endless revolving member being wound around the driving member and driven member, a rail extending along a conveying path of the bread and supporting the first flight, and a rail size setting unit for setting a length of the rail with respect to an extending direction of the conveying path. The length of the rail with respect to the conveying direction is set by the rail size setting unit based on a size of the bread.

An electric wire cutting equipment and a synchronous wire saw are provided. The electric wire cutting equipment includes a synchronization mechanism, a fixing frame, rotating wheels, a driving motor, and a cutting wire. The synchronization mechanism is arranged on the fixing frame. The rotating wheels include a driving wheel and a first driven wheel arranged opposite to each other on the synchronization mechanism. The driving wheel is transmission-connected to an output end of the driving motor. The cutting wire is wound between the driving wheel and the first driven wheel. The synchronization mechanism drives the cutting wire to move along the fixing frame. The synchronous wire saw includes a support frame and the electric wire cutting equipment rotationally connected to the fixing frame.

A cutting apparatus for performing linear cuts of the oblique or vertical type at least on a block of polymeric material includes: a worktable that supports the block to be cut; and a carrier member for a cutting tool designed to cut the block. The carrier member defines a cutting axis for the cutting tool. The carrier member can be tilted with respect to the worktable. At least one of the worktable and the carrier member is movable along a movement direction which is arranged angularly with respect to the cutting axis, so as to vary a distance between the worktable and the cutting axis along the movement direction. At least one of the worktable and the carrier member is movable along a cutting direction perpendicular to both the cutting axis and the movement direction.
