An interfolding machine (1) for producing stacks (100) of interfolded sheets according to a predetermined interfolding configuration, starting from a web (50) of paper, or similar materials, provides a feeding section (10), which provides to apply a tension on the web (50) and to move the same along a feeding direction (101) to feed the same to a cutting section (20), in which the web of paper (50) is cut into a series of sheets (11) of length predetermined, at a cutting point arranged between a cutting roller (25) and a counter-cutting element (26). Downstream of the cutting section (20) a folding section (30) is provided comprising a first and a second folding rollers (31,32) counter-rotating one with respect to the other. The first and second folding rollers (31,32) are arranged to rotate about respective rotation axes (131,132), in such a way to have a first peripheral velocity vP and are configured to fold, at a folding zone (35), the aforementioned plurality of sheets (11) in a plurality of panels and to form the stack (100) of interfolded sheets. The cutting roller (25) is configured in such a way to alternately distribute the aforementioned sheets (11) between a transfer roller (45) of transfer section (40), and the first folding roller (31).

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.

The invention provides a fiber product folding and stacking system comprising at least one folding wheel, a plurality of suction channels, a plurality of valves and a plurality of passages. The folding wheel includes a plurality of protruding wheels and a plurality of recessing wheels. The protruding wheels and the recessing wheels are adjacent to each other, and suction channels are arranged within the protruding wheels. The passages are disposed in the folding wheel and are fluidly connected to the suction channel. The valves are disposed within the recessing wheels of the folding wheel, and include a connecting opening, a valve channel and a valve opening. When the folding wheel rotates, portion of the suction channels will be fluidly connected to the valve channel through the passage and the valve opening to generate a negative pressure thereon for absorbing the fiber product.

A vacuum roller system and a method of operating the vacuum roller system can include a group of vacuum rollers operable to move a sheet of media through a dryer. The vacuum rollers do not require a vacuum to be drawn between the vacuum rollers. Each vacuum roller can include a plenum operable to direct the vacuum to a top portion of the vacuum roller to drive the sheet of media from one roller to the next roller. The plenum can engage vacuum holes in a rotating vacuum roller when the vacuum holes in the vacuum roller are aligned with the plenum.

The disclosure relates to a method and apparatus for uncut material detection while lifting from an automated cutting table select pieces of thin, flexible material. The apparatus comprises a structured energy source and a structured energy sensor. The structured energy can be used to detect undesired lifting of a peripheral portion of the flexible material resulting from the presence of uncut material.

The invention presented and described comprises an apparatus for mounting flat data carriers (1) on a continuous carrier web (2), having a data carrier supply device (3), a data carrier transfer device (4) and a carrier web positioning device (5), wherein the supply device (3) has a drive roller (6), a deflector (7) arranged substantially horizontally spaced apart from the drive roller (6) and at least one carrying belt (8) which runs around the drive roller (6) and deflector (7), wherein the carrying belt (8) has an upper run (9) which runs substantially horizontally in the feed direction of the data carriers (1), and a lower run (10) which runs in the opposite direction below said upper run, wherein the upper run (9) forms a transport path (11) for the data carrier (1) and is hydraulically connected to a suction box (12) which is arranged beneath in such a way that data carriers (1) which are located on the upper run (9) can be drawn by suction onto the carrying belt (8) by negative pressure, wherein the transfer device (4) has a transfer roller (14), which is provided with intake openings (13) on the circumference and which is hydraulically connected to a negative pressure source in such a way that data carriers (1) located on the outer casing of the transfer roller (14) can be drawn by suction onto the outer casing by negative pressure, wherein the transfer roller (14) has an entry region (15) which is adjacent to the suction box (12) of the supply device (3) and an exit region (16), which is spaced apart from the entry region (15) by a specific angle and is adjacent to the positioning device (5), and wherein at the exit region (16) of the transfer roller (14), a data carrier (1) which is located there on the outer casing of the transfer roller (14) can be transferred onto the carrier web (2).
