Abstract: A system includes a drum assembly that includes a support bar having a first end and a second end, and a plurality of drum segments coupled to the support bar. The drum segments are movable between retracted and extended positions, and the drum assembly is configured to be disposed within an interior region of a coil of flexible pipe when the plurality of drum segments are in the retracted position. The system also includes a first containment flange coupled to the drum assembly at the first end, a second containment flange coupled to the drum assembly at the second end, a first coupling device configured to removably couple the first containment flange to the drum assembly, and a second coupling device configured to removably couple the second containment flange to the drum assembly. The first and second containment flanges are configured to contain the flexible pipe.

Abstract: A roll sheet supporting apparatus includes a pair of rotation shafts which are respectively fitted into end portions of the hollow portion of the core tube and configured to support the roll sheet rotatably and capable of being drawn out, an engaging member movable between a projecting position and a retracting position, wherein the engaging member projects from an outer circumferential surface of the each rotation shaft abutting on the core tube to engage with the core tube at the projecting position and retracts inward from the outer circumferential surface of the each rotation shaft at the retracting position, and an engaging member moving unit configured to move the engaging member between the projecting position and the retracting position.

Abstract: In a winder mandrel (1) with radially movable spreading segments (2) which are arranged on the periphery, a mandrel body (3) and a pulling rod (4), the spreading segments (2) and/or the mandrel body (3) and/or the pulling rod (4) are configured as magnets. A method for operating a winder mandrel of this type provides for the spreading segments (2) and/or the mandrel body (3) and/or the pulling rod (4) to be configured as electromagnets, and for the supply voltage of the electromagnets to be switched on during initial winding of the beginning of the strip, lowered during the rolling and raised again when the strip is slipped out.

Abstract: A winder in which the jaws of the mandrel expand automatically by the weight of the reel, without introducing external energy. The winder has a mandrel of horizontal axis (A) whose jaws are expandable by means of links hinged to the end of a sliding pull rod and connected to the frame by a hinged connecting rod. The winder includes a rocker connected to the frame by a fixed pivot axis (D) and to the mandrel by the physical embodiment of the axis of rotation (A), the two axes (D, A) are parallel. The rocker moves the mandrel vertically between a raised loading position and a lowered use position under the weight of a reel and it brings about, simultaneously, sliding of the pull rod, automatic expansion of the jaws, and automatic clamping of the reel.

Abstract: A spool suitable for winding material thereon includes an axially extending body having a proximal end and a distal end joined by an outer surface. An extractor bar is mounted for slidable movement relative to the body for urging material wound onto the body toward the body distal end.
