A converting machine is used to convert sheet material into packaging templates for assembly into boxes or other packaging. The converting machine includes a converting assembly that performs transverse conversion functions and longitudinal conversion functions on the sheet material to create the packaging templates. A fanfold crease sensing mechanism detects the presence and location of fanfold creases in the sheet material. Based on the location of the fanfold creases, the fanfold creases are either cut out of the sheet material, or the sheet material is cut to adjust the position of the fanfold crease in a packaging template.

A folding device for placing an elastomer thin sleeve on a retainer includes a mandrel, one or more rollers, and a drive system. The mandrel is configured to translate relative to a portion of the folding device. The mandrel is adapted to releasably receive the retainer. The one or more rollers are configured to rotate relative to the mandrel. The rotation of the one or more rollers being configured to fold the sleeve onto the retainer. The drive system is configured to translate the mandrel and turn the one or more rollers.

The application relates to a method for zigzag folding a material web, the method having the following steps: continuously feeding a material web to be folded into a folding apparatus along a feed direction, alternately gripping the material web in a proximal region of the folding apparatus by means of gripping devices, holding and conveying the material web by means of the gripping devices into a distal region of the folding apparatus, the material web being zigzag folded thereby, and releasing the material web from the gripping devices and depositing the material web in a stack (9) with folds in the distal region, a distance between adjacent gripping devices (4, 5) being equal to a fold length. Furthermore, the application also relates to an apparatus for zigzag folding a material web.

The invention provides a fiber product suction system, comprising a folding wheel and a plurality of valves. The folding wheel comprises a plurality of protruding wheels and a plurality of recessing wheels adjacent each other. A plurality of suction channels and at least one connecting channel are disposed within the protruding wheel, wherein the connecting channel is fluidly connected to the suction channel. The valve is disposed on the recessing wheel of the folding wheel, and includes a connecting opening, a valve channel and a plurality of valve openings, wherein the valve openings are disposed on two sides of the valve, and are fluidly connected to the connecting opening via the valve channel. An air extractor can extract the gas in each suction channel through the valve, and generate a negative pressure on part of suction channels of the protruding wheel, so that the fiber product suction system can be used to suck and fold paper.

Systems and methods for folding and stacking fanfold corrugated board material. A system may include a rotatable member (e.g., a wheel) having a number of head pieces disposed thereon. Each head piece has a vacuum setting that can be used to pick up a portion of a length of fanfold and hold it while the rotatable member rotates around its axis and a second blower setting that blows the portion of the length of fanfold that was picked up and rotated around the rotatable member down onto a stack of fanfold. Such a system is capable of forming regular and consistent stacks of fanfold material efficiently and cost effectively without the need for significant human intervention.

A converting machine is used to convert sheet material into packaging templates for assembly into boxes or other packaging. The converting machine includes a converting assembly that performs transverse conversion functions and longitudinal conversion functions on the sheet material to create the packaging templates. A fanfold crease sensing mechanism detects the presence and location of fanfold creases in the sheet material. Based on the location of the fanfold creases, the fanfold creases are either cut out of the sheet material, or the sheet material is cut to adjust the position of the fanfold crease in a packaging template.
