CORELESS PAPER ROLL MANUFACTURING METHOD
A manufacturing method includes: a first step for winding up paper to form paper roll; a second step for inserting an insertion section, which ejects an adhesive, into a center hole of the paper roll; a third step for causing the adhesive to adhere to a predetermined position of the center hole; and a fourth step for performing a heating and drying process on an area to which the adhesive is adhered to harden opposite ends of the center hole. The third step includes causing the adhesive to adhere to near opposite extending ends of the center hole. The adhesive has adhesive strength to an extent that the paper wound up into the roll shape is peelable when the paper roll is to be used. The fourth step includes drying the adhesive adhered to the center hole before the adhesive spreads from the predetermined position of the center hole.
Traverse winding apparatus
An improved winding apparatus and system for winding strips of web materials.
Bladder Rolling Machine
An apparatus for rolling a bladder includes a support structure, a rolling pin, and a bladder-mounting pin. The apparatus optionally includes a rolling initiator Rolling a bladder includes inserting the bladder while unrolled into an apparatus for rolling a bladder, inserting the bladder between a rolling pin and a bladder-mounting pin of the rolling machine, and rotating the rolling pin to (a) advance a portion of the bladder between the rolling pin and the bladder-mounting pin, (b) roll the portion of the bladder around the bladder-mounting pin, and (c) drive the bladder-mounting pin to rotate in an opposite direction from that of the rolling pin.
METHOD OF PRODUCING A FABRIC ROLL AND ROLL THUS MADE
A fabric roll is produced by winding a fabric (4) around at least two reels, that are coaxially aligned, spaced from each other, and have a total length (L) that is less than the width (Wr) of said fabric roll (11).
Device for removing road tape
A device for removing road tape from a surface comprises a body, and a drive assembly coupled to the body. The drive assembly comprises a motor having a drive wheel, at least one drive belt, a rolling drum drive wheel configured to engage the at least one drive belt, and at least one rolling drum configured to secure an end of the road tape. The rolling drum is configured to rotate in response to rotation of the rolling drum drive wheel and wind the road tape about a circumference. The winding of the road tape drives the body in a forward direction.
TRAVERSE WINDING APPARATUS
An improved winding apparatus and system for winding strips of web materials.
Winding shaft for receiving at least one winding core
The invention relates to a winding shaft (1) for receiving at least one winding core, said winding shaft having a shaft body (2) made of fiber-reinforced plastic, preferably CFRP, having two bearing points (4, 5) at each end of the winding shaft, having radially displaceable clamping elements (20) distributed over the circumference and over the axial length for clamping, holding and releasing the winding cores. The winding shaft is designed to hold winding cores having an inside diameter of a maximum of 80 mm.
Coiler bar assembly
A coiler bar assembly includes a coupler housing and a bearing housing used to suspend a reel shaft above a surface. The reel shaft is configured to include bearings to permit its rotation relative to the housings. The coupler housing includes a receiving plate coupled to an end of the reel shaft and a coupler that is engaged with a motor shaft. The motor shaft extends up to the receiving plate. A handle is included and is pivotally coupled to the coupler housing and the coupler about two separate axes. Pivoting the handle permits translation of the coupler along the motor shaft to selectively engage the receiving plate. When engaged, rotation of the motor shaft induces rotation of the reel shaft. The handle is operated externally from the coupler housing.
Safety chuck
A safety chuck mounted to equipment that process web material is provided. The safety chuck is provided with a die spring connecting a moveable jaw with a spindle, said spring urging the moveable jaw into a fully closed position. A number of magnets mounted on a mounting flange will engage the moveable jaw, overcoming the spring's force and holding the moveable jaw in a fully open position. Rotation of the spindle releases the magnets allowing the spring to force the moveable jaw back into a fully closed position.
Winder and a method for winding a roll from a fibrous web
The present invention relates to a w winder (1) for winding a web roll (2) from a fibrous web such as a paper web or a web of non-woven material paper (2). The winder (1) comprises two support rolls (3, 4) for supporting the web roll (2) during reeling and a core shaft (5) for winding the paper reel (2). At each longitudinal end of the core shaft (5), there is a carrier chuck (6) in which the core shaft (5) is rotatably journalled. The carrier chucks to are arranged to be movable in a frame towards or away from the support rolls (3, 4) and a rider roll (8) is arranged to be capable of acting against the web roll (2) being wound. The rider roll (8) is carried by a rider roll beam (9) and the rider roll beam (9) is arranged to be movable in the frame (7) such that the rider roll (8) can be moved towards or away from the support rolls (3, 4). There is at least one actuator (10) for moving the rider roll beam (9) towards or away from the support rolls (3, 4); and at least one load cell (12) arranged to detect the force between the rider roll (8) and the web roll (2). The winder (1) also comprises at least one actuator (11) for moving the carrier chucks (6) of the core shaft (5) independently of the rider roll beam (9) and the winder (1) comprises at least one load cell (13) arranged to detect the force with which the carrier chucks (6) act on the core shaft (5). The winder (1) also comprises a logic control system (14) connected to the load cells (12, 13) such that the logic control system (14) receives measured values for the force between the web roll (2) and the rider roll (8) and the force with which the carrier chucks (6) act on the core shaft (5). The logic control system (14) is programmed to control movement of the carrier chucks (6) and the rider roll beam (9) such that the sum of the forces detected from the load cells (12, 13) and the force resulting from a calculated weight of the web roll (2) corresponds to a set value for the force between the web roll (2) and the support rolls (3, 4). The invention also relates to a corresponding method for operating the winder.
