A dunnage conversion system includes a machine for converting a stock material into a strip of relatively lower-density dunnage, a coiling mechanism for winding the strip into a coil, a taping mechanism for automatically securing a trailing end of the strip to the coil, and a coil ejecting mechanism for automatically removing the coil from the coiling mechanism. The taping mechanism includes a guide surface between an outlet of the machine and the coiling mechanism to guide the strip to the coiling mechanism and to guide tape for engagement with a trailing end of the strip and to secure the trailing end of the strip to the coil. The coil ejecting mechanism includes a lever arm that pivots to push the completed coil off the coiling mechanism.

The present disclosure relates to a method performed by an alignment system for aligning tethers of a drop stitch fabric prior to feeding the drop stitch fabric to a drop stitch fabric processing machine. The alignment system feeds a drop stitch fabric having a first layer and a second layer tethered by drop stitch tethers, wherein the first layer is moving with a first velocity and the second layer is moving with a second velocity. The disclosure also relates to an alignment system in accordance with to the foregoing.

A transporting apparatus includes a pressurizing roller that transports a web-like or sheet-like transport target object and a heating roller disposed downstream of the pressurizing roller in a transport path, a first bottom sensor and a first top sensor that are disposed between the pressurizing roller and the heating roller, a measuring section that measures a time from when the transport target object is detected by the first bottom sensor until the transport target object is detected by the first top sensor, and a rotation control section that modifies a rotation speed of the heating roller when a time measured by the measuring section is shorter than a first reference time.

A suction device configured to reliably support or transfer a fiber material web made from glass fibers, fleece material or paper, the suction device including a first guide roller and a second guide roller; a suction box arranged between the first guide roller and the second guide roller; and a permeable clothing that runs over the first guide roller, the second guide roller and the suction box, wherein the suction box includes an operating surface configured to impart a vacuum upon the permeable clothing that runs over the operating surface and upon the fiber material web transported on the permeable clothing during operations, wherein the operating surface is arranged and sized so that it essentially bridges an entire path traveled by the clothing between the first guide roller and the second guide roller; an additional guide roller and an additional suction box over which the permeable clothing is run.

A method and an apparatus for horizontally splitting a mineral wool web includes a conveyor having a first direction of travel adapted for receiving and advancing a cured mineral wool web in said first direction. At least one dividing device is provided for longitudinally dividing the cured mineral wool web into at least two sub-webs as said cured mineral wool web is advanced passed said at least one dividing device. At least one lifting mechanism is provided downstream of the dividing device so that a section of the conveyor is adapted for lifting a sub-web. At least one horizontal cutting device is provided for horizontally cutting the sub-web whilst lifted in said conveyor section.

A variable roll cage machine and process to roll up material, like high expansion force material. The machine includes a roll chamber to receive the material. The roll chamber has a longitudinal central axis and a plurality of rollers located around a circumference of the roll chamber. The plurality of rollers include two roll groups of at least two rollers in each roll group. At least one of the rollers in each roll group is movable toward the longitudinal central axis independent of at least one other roller in the roll group. A material infeed gap is in the circumference of the roll chamber located between the two roll groups and spaced from the at least one of the rollers in each roll group that is movable.

A dunnage conversion system includes a machine for converting a stock material into a strip of relatively lower-density dunnage, a coiling mechanism for winding the strip into a coil, a taping mechanism for automatically securing a trailing end of the strip to the coil, and a coil ejecting mechanism for automatically removing the coil from the coiling mechanism. The taping mechanism includes a guide surface between an outlet of the machine and the coiling mechanism to guide the strip to the coiling mechanism and to guide tape for engagement with a trailing end of the strip and to secure the trailing end of the strip to the coil. The coil ejecting mechanism includes a lever arm that pivots to push the completed coil off the coiling mechanism.

The machine (1) comprises: —an unwinding section (3) for unwinding parent reels (Ba, Bb) of web material (N; S); —at least one winding station (15) comprising a winding device (25) and further comprising: guide members for guiding the strip (S) of web material, configured to form at least a loop of web material between a guide roller (43) and a log (B); and a cutting device (61) for transversally cutting the strip (S) of web material in an intermediate position between the log (B) and the guide roller (43), thus generating a tail edge, remaining on the log (B) being formed, and a leading edge, remaining fastened to the guide roller (43).

A system and method for lifting substrate sheets off of a stack of porous sheets one at a time, even though the sheets tend to stick together. A felt tamp is lowered onto the stack of sheets, and as the tamp is raised, a set of edge flickers create a downward force on the corners of the top sheet. This causes the edges of the top sheet to bend downward slightly just enough to pry the second sheet loose from the top sheet. The tamp can then be further raised with only the top sheet adhering to the felt, and the lifted sheet can be deposited at the next station in the process. Periodically, a brush is used to renew the surface of the felt to prevent matting of the felt fibers.
