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.

Impeller for a centrifugal food cutting apparatus, comprising a base plate and at least one set of paddle parts mounted on the base plate and provided for imparting centrifugal force to food products to be cut. Each set comprises inner and outer paddle parts defining at least a first stage and a second, cutting stage, the inner and outer paddle parts being offset from each other in radial and angular direction of the impeller, such that a safe compartment is defined for food product which is in the second stage.

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.

A fiber product folding apparatus includes a first dashed-line cutting device used to form a plurality of first dashed lines on a first fiber product. Through control of the rotational speed of the first dashed-line roller, the interval between adjacent first dashed lines is adjusted. A first severing device receives the first fiber product with the first dashed lines by a predetermined length and cuts off the first fiber product. A second dashed-line cutting device is used to form a plurality of second dashed lines on a second fiber product. Through control of the rotational speed of the second dashed-line roller, the interval between adjacent second dashed lines can be adjusted. A second severing device receives the second fiber product that includes the second dashed lines by a predetermined length and cuts off the second fiber product. Finally, the first fiber product and the second fiber product are conducted to pass between a first folding roller and a second folding roller to proceed with folding. Since the dashed line interval of the fiber products is the size or length of a single sheet of fiber product, controlling the rotational speeds of the dashed-line rollers would allow for adjustment such that folding can be performed for multiple forms.
