摘要： The present disclosure relates to adjusting and maintaining a position of a cutting surface used to create lines of weakness for rolled products. A perforating apparatus includes a housing rotatably supported by a frame, wherein the housing is adapted to rotate about a first axis. A support member including a first cutting surface is rotatably supported by the housing, wherein the support member is adapted to rotate about a second axis offset from the first axis. A roll including a second cutting surface is positioned adjacent the support member, wherein the roll is adapted to rotate about a third axis. The second cutting surface is adapted to contact the first cutting surface as the roll rotates about the third axis. The perforating apparatus is configured such that the functions of adjusting the position of the first cutting surface and holding the first cutting surface in a fixed position are separate.

摘要： Cutting head for a centrifugal cutting apparatus, comprising cutting stations, each of which has a cutting element at a leading end and an inner wall extending from the leading end to a trailing end and forming a product sliding surface. The cutting stations are assembled adjacent one another with a gap between each pair of adjacent cutting stations, a rake-off angle θR being defined as the angle that a product slice deviates upon being cut by one of the cutting elements and exiting the cutting head through the respective gap, said angle being measured relative to a tangent line to the product sliding surface at the trailing end of the respective preceding cutting element. A rear part of the product sliding surface at the trailing end is adapted such that the rake-off angle θR is below 17°.

摘要： A system that converts sheet material into packaging templates includes a converting assembly that performs conversion functions, such as cutting, creasing, and scoring, on the sheet material as the sheet material moves through the converting machine in a first direction. The converting assembly may be mounted on a frame such that the converting assembly is elevated above a support surface. One or more longhead converting tools performs conversion functions on the sheet material in a first direction and a crosshead converting tool performs conversion functions on the sheet material in a second direction in order to create packaging templates.

摘要： A modular unit configured for mounting to a cutting head of a slicing machine and for securing a knife to the cutting head, and slicing machines equipped with one or more of such modular units. The modular unit includes mounting blocks adapted to be spaced apart in an axial direction of the cutting head, and a clamping assembly assembled with the mounting blocks so as to extend between the mounting blocks. The clamping assembly is configured to secure a knife to the cutting head, and at least portions of the clamping assembly may be removable from the cutting head by disassembling the clamping assembly from the mounting blocks without removing the mounting blocks from the cutting head.

摘要： Disclosed is a tire building apparatus and a method for joining or cutting tire components. The tire building apparatus includes a rocking member that is movable in a rocking plane in a rocking motion along a rocking line, a translation guide extending parallel to the rocking line and a carriage that is displaceable along the translation guide, wherein the rocking member has a convex edge that defines a minor arc of a circle and extends up to a rotation center, wherein the rocking member is supported by the carriage at the rotation center and is angularly displaceable with respect to the carriage about a rotation axis extending through the rotation center.

摘要： A facer facing the ends of polyolefin pipes for butt fusion is modular in the sense that it employs three types of modules, a drive unit, two blade holders and a motor assembly, that are separable from one another and each independently light enough to be hand-lifted along walls and up to ceilings. The drive unit module is adjustable to accommodate different guide rail spacings. The blade holder modules are interchangeable to accommodate different diameters of pipe. The motor assembly module has multispeed capability to accommodate the total area of material to be faced. Each module can be exchanged or modified without use of tools to change the geometry of the assembled facer to accommodate different fusion machines and/or diameters of pipe within working spaces dictated by the diameter of the pipe and not by a fixed geometry of a facer.

摘要： A flexible curvilinear knife is disclosed. The flexible curvilinear knife is formed from a cutting element, a blade holder element, and a plurality of spring elements. A first, proximal end of each spring element of the plurality of spring elements is operably and fixably attached to a discrete location of the cutting element and a second, distal end of each spring element of the plurality of spring elements is fixably attached to a discrete location of the blade holder element.

摘要： A wrinkle caused in a separator roll is inhibited. A slitting apparatus (6) changes a conveying direction of a first separator (12a) by a direction changing roller (68) toward a first take-up roller (70U), and conveys the first separator via an assisting roller (69) which is provided between a take-up position of the first separator to be wound and the direction changing roller so as to shorten a conveying distance between the take-up position and a roller immediately before the take-up position.
