| 20100065675 | EXPANDABLE BELT MANDREL - This is a mandrel used to fabricate seamless belts including those used in electrophotographic marking systems. The mandrel has a center core unit with two circular caps on each side. In between the caps is sandwiched a deformable O-ring which is outwardly deformed upon tightening of the two caps together. Once a tubular sheet is placed over the mandrel, the elastomeric O-ring will hold the sheet in place for further processing. | 03-18-2010 |

| 20130186997 | CORE FOR AN ENDLESS WEB OF A PLASTIC FILM - A core which can be plugged onto a winding shaft for winding an endless, flexible material web to form a reel ( | 07-25-2013 |
| 20130193260 | WINDING SHAFT FOR A WINDER - The invention relates to a winding shaft for winding a continuous flexible material web into a roll. The winding shaft has means in order to adjust the diameter of the winding shaft surface to be wound between a reduced-diameter unused position and an expanded operating position, and the winding surface in the expanded position is formed jointlessly with a uniform curvature and is supported inward against the operational pressure around said winding surface in a dimensionally stable manner that is substantially uniform. A roll can thereby be wound without disruptions and then stored without a casing until the roll “dies”, said roll remaining stable during storage and not forming any disrupted zones on the inner face of the roll. | 08-01-2013 |
| 20140027558 | ELONGATED SHEET FEEDING REEL - A delivery reel for an elongated sheet, having a disk-shaped flange member on which a sheet roll is positioned; an auxiliary core member of generally cylindrical shape split in the circumferential direction to enable expansion in diameter, and inserted into the inside diameter part of the sheet roll; a main core member fitted into the auxiliary core member which has been inserted into the sheet roll; and a stopper member attached to the circumferential edge of the flange member, and jutting toward the outside in the radial direction. The main core member has a plate spring. In a state in which the auxiliary core member has been inserted into the inside diameter part of the sheet roll, and the main core member has been fitted into the auxiliary core member, the plate spring presses the inside peripheral surface of the auxiliary core member toward the outside in the radial direction. | 01-30-2014 |
| 20140042262 | EXPANSION DEVICE FOR HOLDING AND SECURING ROLLED MATERIAL - An expansion device configured for securely holding a rolled material when the rolled material is handled on roller is disclosed. The expansion device includes a roller spindle, two expansion members, a fixing sleeve, a clamping nut, and a locking member. The locking member moves toward the expansion members, so that the two expansion members expand toward the fixing sleeve, and protrusions which are formed on the expansion members are pressed outward through fixing holes of the fixing sleeve, and then resist against an inner surface of rolled material inside a rolling hole formed therethrough the rolled material. Thus, the rolled material is held securely by the expansion device. | 02-13-2014 |
| 20150360904 | Mandrel with Wire Retainer - A mandrel for the winding of wire includes a central element and segments radially extending about and respectively coupled to the central element by rotatable arms that permit the segments to assume a collapsed position and an extended position Inner surfaces of the segments define slots in which ends of the arms extend.

A resilient pad is fixed in the slot of that segment and has a face located at the opening and adjacent a surface of an arm coupling that segment to the central element. A wire is threaded into the opening and held in place when the arms are rotated to cause the segments to assume the extended position. Methods using the mandrel are disclosed. | 12-17-2015 |

Each outer ring has an annular array of slots in which are elongated rotatable gripping cylindrical rollers having arcuate edges. Each roller is resiliently urged radially inwardly by an O-ring against the camming surfaces. The camming surfaces selectively urge the rollers outwardly to grip a core about which filaments are to be wound. An array of recesses in the outer ring receive a corresponding pad of fibrous members such as the hook type fasteners available as Velcro and Velcoin brands for initially frictionally engaging and gripping a received core. The fibrous members extend from a substrate having an adhesive backing for securing the pad to the recesses. | 10-02-2008 |

| 20150129710 | Mandrel for stretch film rolls - An adjustable mandrel for use with cored, or coreless rolls of stretch film is disclosed. The mandrel comprises a cylindrical shaft and a sheath. The shaft and sheath each comprise slanted regions that slide against each other when the shaft is moved relative to the sheath, and this sliding movement causes the radial displacement of the sheath such that the mandrel expands to press against the inner surface of a roll of stretch film. The displaced sheath portions retract when the shaft and sheath are disengaged and can be moved from the roll and reused. The even pressure exerted by the mandrel across the roll prevents deformation of the roll and waste of the film. | 05-14-2015 |

| 20090308968 | PUSH-TO-EXPAND MANDREL FOR STRETCH-WRAP HAND TOOL - The present disclosure relates to a dispenser for use with rolls of film material, particularly coreless rolls. The mandrels of the dispenser can move between a retracted position wherein the dispenser has a reduced diameter, such as for when the dispenser is being inserted into a roll of film, and an increased diameter, such as for when the film is being dispensed from the dispenser. The mandrels have sections which are joined by various spring configurations and are formed as being axially slidable with respect to a central shaft with lug elements. As the mandrel is slid along the central shaft, the lug elements deflect the spring configurations outwardly so as move the mandrels radially outwardly and increase the radius of the dispenser. | 12-17-2009 |

| 20090256023 | Rolled body holder and recording apparatus - A rolled body holder includes a center shaft member serving as a lead screw connected to a handle, a cam member screwed to the center shaft member, and a plurality of segments which form a cylindrical body covering the center shaft member and the cam member. The cam member includes a plurality of rails, and each of the rails includes a cam surface with a radially varying height. Each of the segments includes a follower part fitted to the rail and relatively slidable along the cam surface and an outer surface part on which multiple projections are formed. When the cylindrical body is inserted into a paper tube of a rolled body and the handle is rotated, the center shaft member is rotated to move the cam member in the longitudinal direction. Then, a portion of the cam surface, which is higher in the radial direction, is brought into contact with the follower part, and each of the segments extends in the radial direction so that the projections bite into an inner surface of the paper tube. As a result, the rolled body can be easily and securely held with a simple structure. | 10-15-2009 |
