Abstract:
The winding machine is intended for plastic, laminated, aluminum, paper and self-adhesive materials and comprises two winding shafts (10, 11) which are each provided with a direct-drive motor (13, 14) and which are mounted on a plate (15) that is rotationally supported with respect to a vertical wall (16a) of a framing (16). The plate (15) has associated guides (50, 51) and drive means for moving the motors (13, 14) and shafts (10, 11) linearly with respect to the plate (15). The second end of each winding shaft (10,11) is supported by a carriage (40, 41) that can move in guides (44, 45) provided on a wall (16b), each carriage (40, 41) including a clamp (42, 43) that holds the ends of the winding shafts (10, 11) in a horizontal plane during the formation of a reel on any of said winding shafts (10, 11) and as the reel is moved into an unloading position.
Abstract:
A string emanating from a packaging machine is arranged in a slot by means of a feed inlet and placed in a winding shaft (12). This placement is assisted by the use of positioning brushes (4). After the initial introduction, winding up takes place upon rotation of the winding shaft and upon further engagement of the string in the slot (14) in the winding shaft. The winding shaft is provided on a carrying disc (5) and said carrying disc is also arranged so as to be rotatable. During the first stage, the section of the string emanating from the supply path is pulled with constant force. After the string has been separated from the remaining material, the winding is carried out. Subsequently, the rotating shaft with the string, through rotation of the carrying disc, reaches a next position in which pressing the reel and thus adhesion of the reel end moves the winding shaft out of the reel. The reel has already been checked prior to entering the winding device to determine whether it has to be inspected.
Abstract:
A drum support arm supports a cutting drum with a sector cross section and a receiving drum with a circular cross section, and moves between a web winding changeover position for causing the receiving drum to contact a core and a spacing position for keeping the receiving drum away from the core. The guide roller moves between an approaching position for lifting a web from the receiving drum and a retracted position for causing the web contact a peripheral surface of the receiving drum. When the drum support arm moves to the web winding changeover position, the guide roller moves to the retracted position, and when the drum support arm moves to the spacing position, the guide roller moves to the approaching position. When the drum support arm is set to the web winding changeover position, the cutting drum rotates once to cut the web. A front end of the web formed by cutting is pressed against the core by the receiving drum and wound around the periphery of the core.
Abstract:
An apparatus for forming a roll of contaminant removal tape and methods of forming rolls of contaminant removal tape. The apparatus includes a turret assembly having a first winding cylinder, a first vacuum source providing vacuum to the first winding cylinder, and a web breaking assembly moveable between a first web breaking assembly position and a second web breaking assembly position. The web breaking assembly includes a blade, which is moveable between a first blade position and a second blade position.
Abstract:
A web winder of a turret winding type is provided with a first spindle secured to a first drive shaft. A second spindle is secured to a second drive shaft. Positions of the first and second drive shafts are changeable in the web winder. A changeover device changes over winding of a web wound about the first spindle to winding about the second spindle. A cutting drum is disposed on a first side with respect to a web path of the web, and has a cutter for cutting the web in a width direction thereof. A receiving drum is disposed on a second side with respect to the web path opposite to the first side. A drum support arm supports the cutting and receiving drums in a rotatable manner and in a manner of contacting drum peripheral surfaces of the cutting and receiving drums on each other.
Abstract:
The invention is a centerwinder for receiving and winding web material sequentially on one of at least two fixed shafts. The two or more shafts are desirably positioned vertically to one another in a stationary structure and eliminate the need for a powered turret assembly. A lay-on roll assembly can be used that pivots in and out as well as up and down for serving the respective shaft locations. A cylinder linkage provides the same or constant force against the winding roll on either the upper or the lower shaft. Transfer rolls in desirable embodiments are automatically pivoted into the proper position for a fully automatic transfer or to assist the operator during a manual cut and transfer.
Abstract:
The re-reeling machine comprises a feed assembly (5) for feeding tubular winding cores and a re-reeling assembly (3) with a revolver unit (57) on which the tubular winding cores (C) are set in order to wind on them predetermined amounts of web-like material and form respective rolls (B) of wound web-like material. The revolver unit rotates about an axis of rotation (A) and has at least two supports (101, 102) for tubular cores, which are set in two angular positions with respect to said axis of rotation. The tubular-core feed assembly comprises a dispensing path (165, 171) for dispensing tubular cores to a core loader (181). The core loader is provided with a motion of approach to the revolver unit and a motion of following of the movement of the revolver unit, in order to transfer the tubular cores from the loader to the revolver unit.
Abstract:
An apparatus for drying, cooling, winding up and transverse cooling of a paper web. A lopping device is provided downstream of a conveyor segment lifting the web over the winder or sheet cutter, whichever is proximal to the cooler, the paper web then reaching a bifurcation from then which it may be directed to engagement with the mandrel in a winding readiness position of the coiler or to a conveyor segment for the transverse cutter.
Abstract:
A waste sheet part forming apparatus forms a waste sheet part in a weblike heat transfer recording sheet supplied from a supplying apparatus. A slit apparatus cuts the recording sheet in the longitudinal direction into plural columns, and thereafter the cut recording sheets are sent to a winding apparatus. Sheet rolls formed in the winding portion in the winding apparatus are sent to a discharging portion and cores are supplied to the winding portion. The waste sheet extending between the winding portion and the discharging portion is cut by a cutting portion. An adhesive tape on the upstream side of the waste sheet is attached to a core in the winding portion and an adhesive tape on the downstream side is attached to the outer periphery of the sheet roll in the discharging portion.
