A winding machine includes an upper winding roller and a separation mechanism arranged at a location close to and below the upper winding roller. The separation mechanism includes a pivot shaft having an outer circumferential surface and at least one pinch arm having a connecting end coupled to the outer circumferential surface of the pivot shaft and a web engagement end extending outward from the outer circumferential surface of the pivot shaft. 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.

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.

A tissue paper winding machine includes a first winding roller and a web separator arranged below the first winding roller. A tissue paper is fed into the winding machine to bear against a lower circumferential surface of the first winding roller and moves along a predetermined feeding direction for winding around a core. The web separator includes a pivot shaft, at least one pinch arm having a connecting end connected to the pivot shaft and a pressing end radially outward extended from the pivot shaft, and a driving mechanism for driving the pinch arm to turn about the pivot shaft reverse to the feeding direction of the tissue paper. When the pressing end of the pinch arm is turned to a separation position, it cooperates with the first winding roller to clamp the tissue paper therebetween, and applies a reverse pulling force to split the tissue paper.

A tissue paper winding and cutting apparatus includes a first winding roll, at least one core support plate, a pinch roller, and at least one arm. A channel is formed between the core support plate and the first winding roll. A tissue paper is attached to a lower half of the first winding roll for winding around a first core. The pinch roller is arranged below the first winding roll to partially project into the channel, and the arm is extended to a lower side of the first winding roll and has a bottom protuberance facing the pinch roller, so that a narrowed passage is formed in the channel. A second core rolling to and hindered by the narrowed passage holds the tissue paper thereto, and the tissue paper is pulled broken by a pulling force from a rolled tissue formed on the first core.

A log multiprocessing apparatus winds a web material around a winding core to form a log. Once the log is about to be completed, the web material is severed to form a tail of the log, and a pattern including at least one glue layer is applied on the tail of the log. The log then is decelerated and the tail is pressed on the log to form a final sealed log of web material.

A winding device with a planetary-roller tear-off mechanism is disclosed, comprising a first winding roller which is driven to rotate in a predetermined direction and a plurality of core support plates that are arranged at a predetermined distance below the first winding roller, wherein an interval between the core support plates and the first winding roller is defined as a curved channel. A web material is conveyed through the curved channel to a winding zone to be wound as a roll. The planetary-roller tear-off mechanism includes a plurality of rotary arms and a plurality of planetary rollers. Each rotary arm is set at a predetermined location below the first winding roller, and having a driving end and a free end. Each planetary roller is rotatable, and mounted to the free end of the respective rotary arm. When the free end of the rotary arm is driven to rotate to a position facing a circumferential surface of the first winding roller, the web material is subjected to a drag force acting thereon to break the web material.

Disclosed are a method and a structure for cutting off web in a winding machine. The winding machine includes an upper winding roller having a circumferential surface close to and below which a cut-off mechanism is arranged. The cut-off mechanism includes a pivot shaft having an outer circumferential surface and at least one pinch arm having a connecting end mounted to the outer circumferential surface of the pivot shaft and a web engagement end extending outward from the outer circumferential surface of the pivot shaft and forming at least one suction opening. At least one cutting blade is provided on the web engagement end of the pinch arm at a location immediately by the suction opening. When the pinch arm is driven to rotate the web engagement end to an engagement position where the web engagement end opposes the upper winding roller, the suction opening of the web engagement end sucks and holds 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 and is thus stretched to have the cutting blade set in tight engagement with the web material to cut off the web material.

A gluing mechanism incorporating a notched glue scraper and a method thereof are disclosed. A glue dispensing roller is provided adjacent to a web material traveling path where a web material is conveyed to get past, and operated to touch glue contained in a glue tank, and accordingly, a glue carrying roller surface of the glue dispensing roller is coated with the glue. A notched scraper blade, which faces the glue carrying roller surface of the glue dispensing roller, scrapes the glue stayed on the portion of the glue carrying roller surface, which corresponds with the non-notched area of the scraper edge. Comparatively, the glue stayed on the rest of the glue carrying roller surface is formed a glue layer for subsequently applying to a gluing side of the web material, wherein the rest of the glue carrying roller surface corresponds with notched area of the scraper edge.

A web material winding machine includes a core tube storage tank, a guiding unit, a transmission means, a web material feeding assembly, a gripping assembly and a second gluing mechanism. A core tube is glued with initial glue and conveyed from the guiding unit to the transmission means. Meanwhile, the web material is fed by the web material feeding assembly to the transmission means at a normal speed. The transmission means pushes the core tube to move through a transporting passage to the gripping assembly and the web material is stuck to the core tube. The web material winds around the core tube at the winding region. When the winding is nearly completed, a new core tube is conveyed to the transporting passage and interferes the speeding of web material, causing the web material to tear along the perforation line. A tail glue is applied to the completed core tube by the second gluing mechanism and a roll is produced.
