A system for winding wire includes a wire take-up unit and a wire cutter/grabber unit. The take-up unit includes rotatable first and second mandrel portions, and a wire directing traverse arranged to feed wire and alternately form coils on the first and second mandrel portions. The cutter/grabber unit is configured to cut the wire at a cut position between the traverse and a coil formed on the first mandrel portion and to grab a free end of the cut wire and move along a predefined cutter/grabber pathway to a hand-off position where the wire is transferred to the second mandrel portion. As the cutter/grabber is moved along the pathway from the cut to the hand-off position, a length of wire between the traverse and the free end of the wire does not decrease, and that length of wire is longer at the hand-off position than at the cut position.

Systems and methods are provided for a rotational wire transport. In certain examples, the rotational wire transport may be a part of a wire processing system. The rotational wire transport may include a winding spool, a linear actuator, a cam, and a gripping tab. The rotational wire transport may be configured to wind wire into a coil and move between a plurality of different stations within the wire processing system.

A suspended surface assembly is provided having a trainable surface support element, a spindle component configured for training of the trainable surface support element therearound, a take-up action module configured to drivingly rotate the spindle component to thereby effect winding of the trainable surface support element onto the spindle component or to effect unwinding of the trainable surface support element from a partially or fully wound-up condition, and a lift complex for adjusting the vertical position of the trainable surface support element and the spindle component, the lift complex including a motive power element operable to both drivingly rotate the spindle component and to drivingly raise and lower the trainable surface support element and the spindle component. A method for operating the suspended surface assembly is also provided.

A spool assembly configured to support a roll of material. The spool assembly comprises a first and second flange coupled together via a first and second arbor member. The first arbor member is slidably coupled within a first at least one slot of the first flange and slidably coupled within a second at least one slot of the second flange. A biasing member is coupled to the first arbor member such that the first arbor member is biased radially inward toward a longitudinal axis of the spool assembly. Rotation of the first flange relative to the second flange causes the first arbor member to translate within the first at least one slot and the second at least one slot causing a change in the arbor diameter.

An end plug for coreless paper rolls includes a central body. At least three resilient elements protrude from the central body and press resiliently against the interior of a paper roll when the end plug is inserted into an end of the paper roll, the radial extension of the resilient elements being influenced by rotation of the plug or a part thereof.

A chuck includes a central shaft defining an axis of rotation, a cam seat defined by the central shaft, and a support portion partially defining a first cavity having a first orifice at a first distal end of the support portion, the first orifice operative to engage the central shaft. The support portion includes The chuck further comprises a second orifice defined by the support portion, an expansion portion arranged in the second orifice such that the expansion portion is operative to move radially in the second orifice with respect to the axis of rotation, and a follower member arranged in the cam seat. The expansion portion includes an arcuate profile comprising a core relief feature having a spacer member arranged on a portion of the support portion, the spacer member operative to impede motion of a core of a roll of material along the axis of rotation.

A stepless adhesive film dispenser includes a first tube and a second tube fitted on the first tube, and two operating rings are respectively fitted on the circumferential side of the first tube and the second tube and able to rotate freely along the outer circumferential side of the first tube and the second tube. Thus, an adhesive film reel fitted on both the first tube and the second tube can be restrictedly positioned by the operating rings, which can be rotated together with the adhesive film reel. By so designing, when the stepless adhesive film dispenser is used, a user's hands that hold the first tube and the second tube can be avoided rubbing against the adhesive film reel, hence facilitating operation and use of the stepless adhesive film dispenser.

A roller for supporting a material according to an embodiment of the present invention includes: a rotation shaft; a pipe having a space in which the rotation shaft is inserted; a deforming part that is connected to the rotation shaft and the pipe to deform the pipe; and a support part that is installed at the pipe to support the material. The deforming part includes: a thread portion provided on the rotation shaft; a nut part screwed to the thread portion; an inclined part that is disposed at an inner surface of the pipe and that is pressed by the nut part according to rotation of the rotation shaft; and a driving source that is connected to the rotation shaft to rotate the rotation shaft.
