A medium supporting device including a support part configured to support a roll body on which a sheet shaped medium is wound, a shaft serving as a rotary axis of the roll body and secured with the support part, and a driver configured to rotate the roll body supported by the support part. The shaft is secured to the support part by using a metal plate having a flat surface provided with an insertion hole, the insertion hole being a hole into which the shaft is inserted. An outer circumference part of the metal plate is restricted from moving in a rotation direction of the roll body relative to an inner circumference part of the support part.

A spool endform assembly includes an endform with a central collar that are configured to rotate about a rotational axis. The spool endform assembly further includes a mount sub-assembly configured to be mounted in a fixed orientation on a mounting structure (such as movable arm). The spool endform assembly is further configured to permit misalignment of the fixed orientation of the mount sub-assembly relative to the rotational axis of the endform and central collar. In embodiments, controlled movement of the mounting structure can be used to connect the spool endform assembly to a rotatable mandrel of a wire winding spool and disconnect the spool endform assembly from the rotatable mandrel. By permitting misalignment of the fixed orientation of the mount sub-assembly relative to the rotational axis of the endform and central collar, the spool endform assembly makes it easier to connect the spool endform assembly to the rotatable mandrel and to disconnect the spool endform assembly from the rotatable mandrel. Other features and aspects are described and/or claimed.

Disclosed is a web handling system that includes a spindle having a spindle magnetic coupling portion and a roll core configured for receiving the spindle for mounting thereon and having a roll magnetic coupling portion, wherein the spindle and roll magnetic coupling portions are configured for magnetically attracting each other to hold the roll on the spindle.

The disclosure provides a material pipe and feeding system. The material pipe comprises: a rotation shaft that is provided with an outer thread on an outer peripheral surface; a housing that is covered around an exterior of the rotation shaft and that is provided with an inner thread and a recess spaced from the inner thread on an inner peripheral surface; a fixing member having an axially extending through hole, the fixing member being provided with an outer thread on an outer peripheral surface thereof matching the inner thread of the housing, and the through hole being provided with an inner thread on a hole wall thereof matching the outer thread of the rotation shaft; and a positioning assembly comprising an engaging member detachably disposed in the recess at one end and fixed to the fixing member at the other end.

A core chuck system (10) comprising a core chuck (11) and a spindle (12) onto which the core chuck (11) is lockable, which core chuck system (10) comprises a ball locking mechanism, a locking button (15) and a cone connection (C).

A protective insert for protecting e.g. coils or rolls of sheet steel or aluminum is disclosed. The protective insert is open and diametrically adjustable. The ends of the protective insert may be adjustably engaged by means of engagement means. The engagement means permit diametrical adjustment and locking of the diameter of the protective insert to a suitable diameter. A method of protecting a portion of an object, in particular a roll of sheet material, having a hollow core, is also disclosed.

A cable caddy with a portable housing stores cable reels. Each reel includes a drum coupled to end caps. Plugs inserted in the end caps are irrotatable with respect to the housing and rotatable with respect to the drum. During transport reels are stacked vertically atop one another with a plug of a first reel inserted in a plug of a second reel.

A pair of flanges attachable to the arbor hole of a reel is disclosed. The flanges provide a mechanism to allow the reel to be easily loaded, and lifted into place. Once loaded into place, the flanges may include a locking mechanism that locks the reel in place, centered on the flanges. Additionally, the flanges are attachable using a hub that allows them to rotate independently from one another, and from the reel to which they are attached.

A film dispenser for use in unwinding film from coreless film rolls. A first dispenser member is selectively matable with a second dispenser member. The first and second dispenser members can be mated together in at least two angular positions. The position of a radially outward facing surface of the dispenser can be adjusted based on the angular position of the dispenser members so that the dispenser can firmly engage and support film rolls of varying internal dimensions. Each of the dispenser members can have a radially extending support wall. The support walls define complementary interlocking formations. When the dispenser members are mated together, the complementary interlocking formations engage one another to form a rigid connection between the dispenser members. The engaged support walls radially support a central region of the film roll.

An apparatus for stabilizing a roll of material includes a first and a second conical base. The first conical base has a first through-hole extending completely through the first conical base along a first central axis. The first conical base also has a first tapering section circumscribing and concentric with the first through-hole, the first tapering section configured to be inserted into a first opening of a central bore of the roll. The second conical base has a second through-hole extending completely through the second conical base along a second central axis. The second conical base has a second tapering section circumscribing and concentric with the second through-hole, the second tapering section configured to be inserted into a second opening opposite the first opening of the central bore of the roll. Engagement between the roll and the first and second conical base structures operably stabilizes rotation of the roll.
