A labeling device comprising a guide frame, rotatably supporting a label roll formed by winding around a core a label holding band, which releasably holds a plurality of labels in series, and a peeling member which peels the printed label from the band by bending the band at an acute angle towards a slanting lower part in relation to the direction of movement of the band. The labeling device comprises a guide unit that is pivotally provided for nipping and holding a leading edge of the label holding band in front of the peeling member and is rotatable around the peeling member with the leading edge of the band so that the leading edge of the band is automatically brought to a feeding roller arranged on the slanting lower part of the peeling member in relation to the direction of the movement of the label holding band.

A sheet conveyance apparatus for winding a sheet around a rotator, pulling the sheet wound around the rotator, and sending out the sheet includes a guiding unit that guides a sheet side end pulled from the rotator. The guiding unit forms a slack in the outer periphery of the sheet wound around the rotator, and guides the side end of the sheet sent from the rotator.

A device includes a winding rotary member having a cylindrical shape; a holder having a rotating member, which is provided in the vicinity of a cylindrical surface of the winding rotary member, capable of nipping and conveying the sheet; a first driving mechanism configured to rotate the winding rotary member; and a second driving mechanism configured to rotate the rotating member. The winding rotary member rotates with the sheet is nipped with the rotatable holder, whereby the sheet is wound around the winding rotary member.

The invention concerns an apparatus and a method for winding strips of material not intended for processing, in particular within an apparatus for joining a web of material running off a first reel to a web of material running to a second reel. Known apparatuses have a winding element with a receptacle for the web of material or strip of material, the strip of material being taken up by rotating the winding element. However, it is problematic that the web of material or strip of material slips out of the receptacle during winding, so that reliable take-up is not ensured. By means of the invention, namely, the arrangement of an element for holding the web of material or strip of material in the region of the receptacle, the web of material or strip of material is reliably caught and held, in particular even after the strip of material is separated from the web of material.

A roller is provided with a clamping mechanism that clamps into a closed position upon rotation of the roller in a winding direction, and unclamps into an open position upon rotation in an unwind direction. The roller has a split-core comprising two hollow, semicircular, core halves that toggle between the clamped and unclamped positions when pivoted about a pivot point that is concentric with the rotational axis of the roller. A snap-pivot mechanism provides a snap-action between the core halves by a leaf spring positioned between the core halves. The rotationally free core half is maintained in a fixed position by a pivoting retractable spring plunger engaging a tab on the core half, while the driven core half is rotated toward the fixed free core half, causing the leaf spring to snap to an over center position and clamp the core halves together.

A band winding apparatus for forming a bead core comprises a winding device which is composed of a drum and holding means. The drum is rotatably supported by a support shaft and has a peripheral surface on which a band for forming a bead core is wound. The holding means are installed in the drum and has a holding surface capable of detachably adsorbing a start end of the band outside in the drum's radial direction. The holding surface is arranged approximately flush with the peripheral surface of the drum.

A spool (10) has a first elongate slot (22) in an outer surface (12) of the spool (10) core for receiving an end portion (14a) of a strip (14) of web material, such as a strip of photographic film. The core surface has another elongate slot (24) for receiving the flange (26b) of a clip (26) used for retaining the web material on the spool. The clip has a semi-cylindrical portion (26a) that surrounds the spool core and holds part of the web material against the core surface.

The disclosure relates to an improved core for holding web material. The core includes a cylinder having an axis of rotation and an axially extending slot for receiving the web material, a rectangular collar within the cylinder to form an annular channel and an annular channel floor between the cylinder and the column to maintain a substantially concentric relation there between. The core also includes first, second and third tapered rib members for positioning the web material within the annular channel and a channeled wall member mounted on the rectangular collar opposite a tapered rib member; a post is included within the annular channel in combination with a fourth tapered rib member adjacent thereto. A labyrinth of web material formed by threading an end of the web through the slot into the annular channel along the outer peripheral surface of the rectangular collar, adjacent a first tapered rib member, between a second tapered rib and the channel wall member, adjacent a third tapered rib around the post and adjacent the fourth tapered rib member winding back through the channel and out the slot. The cooperative action of the restraining effect of the post and adjacent wall on the web material, the extended frictional contact between the resulting two layers of web material and the frictional engagement of the web material about the outer peripheral surface of the rectangular collar securely restrain the web to the core during both winding and unwinding operations.

A slip-lock type take-up reel for roll film has drive and driven flanges provided with axial cores that allow limited relative rotary movement of the flanges between a slip position where the cores are radially spaced to receive or release a film end and a lock position where the film end is gripped in interference fit between the cores.
