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.

A wrinkle or misaligned winding caused in a separator roll is inhibited. In a slitting apparatus (6), a conveying direction of a first separator (12a) is changed to a first take-up roller (70U) side by a direction changing roller (68), the first separator is conveyed via a take-up assisting roller (69) which is provided between the direction changing roller and a first touch roller (81U) so as to shorten a roller-to-roller distance to the first touch roller, and the first separator which is being wound is pressed onto a take-up surface by the first touch roller.

An improved winding apparatus and system for winding strips of web materials.

Rewinder for the production of logs. A feeding element adapted to supply a paper web. A guide element adapted to guide sequentially several cores along a predetermined path between a station for feeding the cores and a winding station in which a predetermined amount of the web is wound on each core. A winding element adapted to wind the paper web on the cores in the winding station. The guide element includes a guide with a curved end section that ends in the winding station and in cooperation with the winding element, delimits a channel crossed by each core before reaching the winding station.

The invention relates to a method for adapting at least one winding parameter of a winding device during winding of a film web on a winding core, having the following steps: conveying of the film web along a measuring path between a first driven roll and a second driven rollincreasing of the web tension of the film web between the first roll and the second rollcontinuous detecting of the drive parameters of the first roll and of the second roll at least in the form of the torque and the circumferential speed, determining of a stress-strain diagram from the detected drive parametersadapting of at least one winding parameter of the winding device on the basis of the determined stress-strain diagram in order to achieve a defined elongation of the film web during winding on the winding core.

A device for rolling up and unrolling a floating mat. The device of the invention includes an elongated hollow cylinder having a first end and a second end. The cylinder has an elongated slot formed therein which extends between the ends thereof. A mat retainer bar is positioned in the cylinder. One end of the mat extends inwardly through the slot in the cylinder and is secured to the mat retainer bar. End cap assemblies are secured to the ends of the cylinder and have a lever secured thereto. The mat may be rolled up on the cylinder or unrolled from the cylinder by rotating the cylinder by way of the levers. The levers may be pivotally moved with respect to the end cap assemblies so that they may be stowed in the end cap assemblies and the ends of the cylinder.

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.

An apparatus (un-interleaver) for unwinding a roll of material interleaved with another material, and for separating the materials, includes a first platform, a second platform, a tension-sensor, an edge-sensor, and a controller. The controller monitors signals generated by the tension sensor and the edge sensor, and in response to the signals: a) causes the speed at which the second platform rotates to change to maintain a predetermined tension in the second material as the second material travels from the first platform toward the second platform, and b) causes the second platform to move relative to the first platform to align the edge of the second material traveling toward the roll of second material with the edge of the second material in the roll.

A peeling apparatus according to an embodiment includes: a conveyance roller configured to convey a laminate made by peelably laminating a first substrate and a second substrate including an opening; a peel roller arranged facing the conveyance roller with the laminate interposed in between, and configured to peel the second substrate from the first substrate; a winding roller arranged away from the peel roller, and configured to wind the second substrate peeled from the first substrate; and an auxiliary winding roller arranged between the peel roller and the winding roller, and including a stepped portion configured to maintain a width of the opening.

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.
