The lubrication device delivers a lubricant to the perforating device which provides intermittently spaced cuts to a moving web, also referred to as perforations. The lubrication device includes a retaining member, a plenum, and a comb having a plurality of comb channels. The plenum and the plurality of comb channels are in fluid communication with one another and deliver a lubricant to the perforating device. Lubrication of the perforating device in this manner may improve knife life, perforation quality and web handling.

Methods of separating and positioning discrete articles formed from a continuous length of articles are provided. The methods may comprise the steps of receiving a first portion of the continuous length on a first head in a receiving position of an orbit about a first rotational axis and receiving a second portion of the continuous length on a second head in the receiving position of the orbit about the first rotational axis. The methods may comprise providing a laser system configured to produce and direct a laser beam, and ablating a portion of the continuous length of articles intermediate the first head and the second head with the laser beam to separate the first portion of the continuous length of articles from the second portion of the continuous length of articles, thereby forming a discrete article on the first head.

A mechanism and a method for slitting silicone membranes using automated slitting blades is presented. The pattern of slits in the membrane can be adjusted by using a cutting cylinder comprised of a plurality of circular cutting gears assembled in parallel.

The cutting cylinder is of indefinite length, but in the preferred embodiment is approximately 15″ long and 3″ in diameter. The silicone membrane can range in thickness from 0.005″ to 0.01″ inch.

An edge-cutting device performs edge-cutting for cutting away trimmings of a corrugated cardboard sheet toward the front and back when switching between orders is to be performed in a corrugating machine. This edge-cutting device has an edge-cutting knife provided to project from the outer circumference of a cylinder having an axis disposed in the width direction of the corrugating machine; and a control device that, when switching between orders is to be performed, controls the edge-cutting device to perform a first edge-cutting process for edge-cutting trimming of an old order at the first rotation of the edge-cutting knife and a second edge-cutting process for edge-cutting trimming of a new order at the second rotation. The control device includes a calculation device for calculating the order switching time, and a variable control device for variably controlling the time interval between the first edge-cutting process and the second edge-cutting process.

A cutting unit comprising a cutting drum, a drum knife, a counterpart knife, and a double-joint controller that controls swiveling about a first joint, which swivels the counterpart knife between a cutting position and a waiting position, and swiveling about a second joint, which permits adjustment of a knife gap that forms between the counterpart knife and the drum knife in the cutting position. The drum knife is disposed on a circumference of the drum such that rotation of the drum guides the drum knife past the counterpart knife to cut a label when the counterpart knife is in the cutting position. In the waiting position, the counterpart knife is out of active engagement with the drum knife. The second joint permits adjustment of the knife gap such that the knife gap remains adjusted independently of swiveling about the first joint.

A perforation device for a document processing machine comprising a frame, a support member and a blade member attached to the frame. The support member and the blade member are movable relative to each other. The support member is curved and the perforation device comprises a drive assembly configured to move the blade member and/or the support member in a rocking motion such that only a portion of the blade perforates the sheet wherein the portion of the blade member perforating the sheet moves along the length of the blade member as the rocking motion progresses.

Disclosed are apparatus, systems and methods of lubricating a knife which provides intermittently spaced cuts to a moving web, also referred to as perforations. In this manner, the apparatus, systems and methods are useful in both perforating a web and lubricating the knife used to form the perforations. the apparatus, systems and methods disclosed herein improve knife life, perforation quality and web handling.

In order to manufacture a wearable article of the first size, the introduction velocity is set to the first introduction velocity having a high velocity and the arrangement velocity is set to the first the arrangement velocity having a high velocity. In order to manufacture wearable article of the second size having a shorter length in the carrying direction than that of the first size, the introduction velocity is set to the second introduction velocity lower than the first introduction velocity and the arrangement velocity is set to the second arrangement velocity lower than the first the arrangement velocity and the drum velocity is set to a fixed velocity regardless of the size.

The invention relates to a device for producing book cases, box lids or game boards with a cutting mechanism, which is arranged in the region of the blank feed and serves for cutting off the blank corners, wherein each tool pair of cutting cylinder and counterpressure cylinder is accommodated in a common bearing block and the bearing arrangement of the cutting cylinder has two mutually spaced eccentric bushes and a drive element arranged between the eccentric bushes.

A system for cutting a web material and applying the web material on a substrate. The system comprises a feed roll configured to advance a web material. The system includes an anvil roll configured to receive the web material from the feed roll and provide a section of web material having a defined length. The system includes a cutting element configured to cut the web material to form the section of web material. The anvil roll is configured such that the anvil roll surface advances at an anvil roll surface speed. The feed roll is configured to rotate at a first feed roll surface speed that is slower than the anvil roll surface speed and a second feed roll surface speed that is substantially the same as the anvil roll surface speed when the cutting element cuts the web material.
