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.

A cutting mechanism for a roll fiber product comprises two clamping devices for clamping the roll fiber product, and a blade for cutting the roll fiber product. The two clamping devices are respectively connected to a push device. During the cutting process, the push devices drive the clamping devices and the roll fiber product thereon swinging so that the two clamping devices break the roll fiber products to reduce the contact area and the friction between the blade and the roll fiber products. In addition, two clamping devices are respectively connected with a push-pull device for increasing the size of the gap therebetween, so as to prevent the blade from touching the cut roll fiber products. Thus, the cutting mechanism of the present invention is able to reduce the wear rate of the blade, and improve the yield rate of the roll fiber products.

When the pinch arm is driven by a driving mechanism to rotate the web engagement end of the pinch arm to an engagement position where the web engagement end opposes the upper winding roller, the web engagement end of the pinch arm sucks and holds or guides a web material passing therethrough, whereby the web material is subjected to a pulling force induced by a roll of paper formed in a winding nip to tear and thus separate.

A web product folding and stacking machine includes two folding line making wheels, two folding fingers, a first carrier unit, a stoppage unit and a holder. The folding line making wheels and the folding fingers are operated to fold up web products on the first carrier unit to form a stack of interfolded web products. When a stack of a predetermined number of interfolded web products is finished, the stoppage unit is extended out to isolate the interfolded web products. Further, a retractable member of the stoppage unit is extended out to hold down the finished stack of interfolded web products when the stoppage unit is lowered to carry the finished stack of interfolded web products with the holder, keeping the finished stack of interfolded web products in integrity.

A web product folding and stacking machine includes two folding line making rolls, two folding fingers, a first carrier unit, a stoppage unit and a holder. The folding line making rolls and the folding fingers are operated to fold up web products on a pad on the first carrier unit to form a stack of interfolded web products. When a stack of a predetermined number of interfolded web products is finished, the stoppage unit is extended out to have the finished stack of interfolded web products be carried with the holder and the stoppage unit to a predetermined location for delivery. Subject to the effect of the pad on the first carrier unit, web products are effectively folded up and stacked in a neat status.

An opening cutter assembly for forming an opening perforation line in a plastic packaging film by rolling the plastic packaging film between the opening cutter assembly and an anvil roll of a rolling mechanism when the plastic packaging film is fed through the rolling mechanism. The opening cutter assembly includes an opening cutter shaft, at least one opening cutter seat, and at least one opening cutter blade. The opening cutter shaft has at least one containing compartment. The opening cutter seat is installed in and engaged to the containing compartment by a cutter seat mounting mechanism. The opening cutter blade is mounted to each opening cutter seat. When the opening cutter blade gets worn out due to long term operation and must be replaced, simply dismounting the cutter seat mounting mechanism allows the opening cutter seat and the opening cutter blade to be removed from the containing compartment.

A multiply thin paper sheet having a press-to-bond structure is disclosed, including a first thin paper layer having a first stacking surface and at least one second thin paper layer having a second stacking surface. The first and second stacking surfaces are partially overlapped with each other to define a stacking zone provided between the first thin paper layer and the second thin paper layer. After the stacking zone is subjected to a rolling operation by a rolling pressure, a plurality of first pressed sections are formed on the first thin paper layer, having a predetermined height extended according to a given direction, and a plurality of second pressed sections are formed on the second thin paper layer according to the given direction and respectively corresponding to the first pressed sections of the first thin paper layer. At least one portion of each first pressed section and the respective corresponding second pressed section are bonded and formed as a pressed and bonded site, such that the first thin paper layer and second thin paper layer can be pressed, bonded and patterned simultaneously.

Disclosed is a pre-wound sheet cut-off mechanism of a thin material sheet winding device, including a first winding roller, a plurality of curved guide plates arranged at a predetermined distance below the first winding roller and distributed and spaced from each other by a predetermined distance along an axial direction of a shaft of the first winding roller, a plurality of pre-winding plates each coupled between adjacent curved guide plates, a second winding roller, and a rider roller. In a winding operation, a core is conveyed into a curved-guide-plate channel defined between the first winding roller and the curved guide plates to adhere to and pre-wind a thin material sheet that is conveyed to the first winding roller, and is thereafter transported to a winding nip to form a roll with the thin material sheet. The winding speed of the roll is reduced for preparing a next core to reach the pre-winding plates, accordingly, the thin material sheet is slacked, such that the slacked thin material sheet can be pre-wound, thereafter, the thin material sheet pre-wound continuously and the thin material sheet is gradually tensioned on the next core until the thin material sheet is torn apart.

In a mechanism and method for bonding two paper sheets on an interfolding machine, pre-compressing mechanisms are provided on each of two folding rollers to produce compress-to-bond areas on overlapped portions of two thick or air-impermeable paper sheets transferred to the two folding rollers, so that all plies of the two paper sheets at the compress-to-bond areas are compressed to bond together. Thereby, when the interfolding machine operates at a high speed, a plurality of the locally compressed and bonded paper sheets may still be smoothly folded to form a stack of interfolded paper sheets, such as a tissue paper stack or a paper towel stack.

A tissue paper winding and cutting machine includes a first winding roller, at least one core support plate arranged near the first winding roller to form a channel between them, and a pre-winding roller arranged near and below the first winding roller with a circumferential surface facing toward the first winding roller and protruding into the channel to form a narrowed passage in the channel. The pre-winding roller rotates about a shaft thereof in a direction opposite to a predetermined moving direction of a tissue paper to be wound around cores, and at a rotation speed slower than that of the first winding roller. With the rotation speed difference between the pre-winding roller and the first winding roller, a core moved into the channel is temporarily held at the narrowed passage, so that the tissue paper fed into the channel is wound around the core before being pulled broken.
