A sheet winding mechanism includes a detachable winding core, a rotating body coupled to a first end portion of the winding core to rotate the winding core, and a non-rotating body against which a second end of the winding core is pressed. The winding core includes a winding core main body, a first portion which is located at the first end portion and is coupled to the rotating body, a second portion which is located at the second end portion, is movable in the axial direction, and presses against the non-rotating body, a first elastic body which urges the second portion outward along the axial direction, and a sheet holding portion configured to hold an end portion of a sheet. When the rotating body rotates the winding core while the sheet holding portion is holding the end portion of the sheet, the sheet is wound around the winding core.

Winding device for a protection device in an interior compartment of a vehicle having a winding shaft for windably storing a flexible planar structure. The winding shaft is rotatably supported in a supporting structure mounted fixedly to the vehicle. The winding shaft is rotatably mounted at a front end region by a bearing body on a support axle which extends co-axially to the rotational axis of said shaft and is fixedly connected to the supporting structure. The support axle extends toward a center of the winding shaft beyond the bearing body, the bearing body is axially slidably mounted on the support axle, and a position-securing sleeve is provided on the support axle and supported on the bearing body in an axially positively locking fashion and also on a radially thickened portion of the support axle.

A printing apparatus includes: a main body; a cover; a pair of supporters including a movable supporter; a first urging member configured to urge the movable supporter in an approach direction; an engaging member movable between a separated position and an engaged position; and a second urging member configured to urge the engaging member toward the engaged position. When the cover is in an open state, the engaging member is located at the engaged position by an urging force of the second urging member so as to inhibit movement of the movable supporter in the approach direction. When the cover is in a closed state, the engaging member is located at the separated position against the urging force of the second urging member by contact of the cover with the engaging member so as not to inhibit the movement of the movable supporter in the approach direction.

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 12 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.

A recording apparatus includes a printing unit that performs a recording on a sheet, a third sheet feed unit that mounts a roll body on which the sheet is wound in a roll shape, unwinds the sheet from the roll body, and supplies the sheet to the printing unit, and a pressing portion that presses the roll body mounted on the third sheet feed unit, in which the pressing portion presses the mounted roll body in a direction opposite to a direction of taking out the roll body from the third sheet feed unit.

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.

A floating water mat reel that has a plurality of plates mounted to an axle. A floating water mat is selectively connected to the plates. A crank, connected to the axle is used to rotate the plates so that the mat wraps around the plate.

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.

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.

A sheet winding mechanism includes a detachable winding core, a rotating body coupled to a first end portion of the winding core to rotate the winding core, and a non-rotating body against which a second end of the winding core is pressed. The winding core includes a winding core main body, a first portion which is located at the first end portion and is coupled to the rotating body, a second portion which is located at the second end portion, is movable in the axial direction, and presses against the non-rotating body, a first elastic body which urges the second portion outward along the axial direction, and a sheet holding portion configured to hold an end portion of a sheet. When the rotating body rotates the winding core while the sheet holding portion is holding the end portion of the sheet, the sheet is wound around the winding core.
