A cutting apparatus including an apparatus frame and a cutting station, for forming interconnected bags, is provided. The cutting station includes a rotary anvil having an axis of rotation and mounted to a first frame structure, a rotary cutting die disposed adjacent to said rotary anvil and having an axis of rotation parallel to said first axis of rotation, said rotary cutting die including a rotatable cylindrical shaft carrying a die blade, said rotary cutting die being mounted to a frame structure, and an adjustment mechanism for varying the distance between said anvil and said cutting die, said mechanism including a rotatable spindle having threaded portions of different pitch. A first threaded portion engages a threaded portion of said first or said second frame structure and said second threaded portion engaging a threaded portion of said apparatus frame.

A knife assembly includes a knife blade of which a front edge is a cutting edge, a holder for supporting the knife blade, a clamp for clamping the knife blade onto the holder, and a fastening mechanism for securing and clamping the knife blade between the clamp and the holder with the cutting edge protruding at a front side of the assembly. The holder has a frontal portion which is the foremost portion of the assembly at a bottom side of the knife blade and of which a foremost contact point is, in clamped state, in contact with a bottom side of the knife blade at a first distance from the cutting edge. The clamp includes front portions which protrude forward and into valleys of the knife blade and which have leading edges that protrude beyond said foremost contact point and create a crumple zone in front of the holder.

This invention provides web-cutting mechanism that can be mounted in line at an appropriate location between the web-handling peripheral (printer) and a web roll. The cutting mechanism operates before the available storage in the winder festoon has been exhausted, and decouples the roll's energy from the web. The cutting mechanism can employ a blade that is drawn through the web solely by the movement of the web itself. The blade is mounted at a (e.g.) 45-degree angle to web travel, causing it to be pulled through the web. A negator spring assembly and associated cable drives the blade into the side edge of the web when a slide-mounted blade shuttle assembly is released by a latching pawl of a solenoid assembly. The solenoid is triggered by a signal indicating an emergency stop condition, such as an upstream jam.

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.

The manual food processor includes a first shelf configured to receive a blade cartridge. The first shelf includes a first slider configured to selectively retain the blade cartridge at the first shelf. The manual food processor also includes a pair of guide rails extending from the first shelf and a second shelf slidable along the pair of guide rails. The second shelf is configured to receive a pusher block cartridge and includes a second slider configured to selectively retain the pusher block cartridge at the second shelf. The manual food processor also includes a handle mechanism operable to cause the second shelf to slide along the guide rails between an open position and a closed position. The first shelf is spaced apart from the second shelf in the open position, and the pusher block cartridge interfaces with the blade cartridge in the closed position.

A system and method for aligning and installing graphical dies onto an embossing press or foil stamping press is provided. The system includes a number of die support panels having a number of threaded openings disposed in columns and rows in a grid like fashion and identified with x and y axis indicia. The system also includes a number of dies with a number of apertures each identified with a pair of x and y axis indicia. Fasteners and indicia are used to align and attach the dies to the die support panels in a predetermined position. The system preferable further comprises one or more adjusters used to make minute positioning adjustments to the die after it is installed on the panel.

A rotary cutting module for a paper cutting device has a roller and a paper-cutting blade. The roller extends along a rotating axis. A blade mount and multiple dynamic balancing recess sets are formed on an outer circumferential surface of the roller. The dynamic balancing recess sets are disposed apart from each other along the rotating axis. Each one of the dynamic balancing recess sets has multiple balancing recesses annularly disposed apart from each other. A depth of one of the balancing recesses of one of the dynamic balancing recess sets is different from a depth of one of the balancing recesses of another one of the dynamic balancing recess sets. Center of mass of each axial segment of the rotary cutting module can be adjusted individually to mitigate couple unbalance, thereby mitigating dynamic unbalance.

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.

Pipe splitting apparatuses and systems including a replaceable blade, and methods therefor, are provided. In various examples, a pipe splitting apparatus includes an outer surface including a recess. A blade including a portion is disposed within the recess. A hardenable material is disposed within the recess. The hardenable material is configured to flow upon application to fill empty space within the recess and at least partially around the portion of the blade disposed within the recess. The hardenable material is further configured to harden after application to secure the portion of the blade within the recess and fix the blade to the pipe splitting apparatus.
