A spool or reel for carrying spoolable or coilable material comprises first and second sides, a drum disposed there between at least one flange secured to a side and associated with the axis of rotation of the spool. The flange comprises a socket preferably centered about the axis of rotation and configured to receive a replaceable wear hub. The flange and replaceable wear hub are configured to transmit torque there between so that relative rotation between the components is minimized or eliminated.

A spool for winding strand-shaped material having flange discs (22, 24) with an outer flange surface and an inner flange surface (21, 23) as well as a method for manufacturing the spool. The discs have a central through bore (30) that is surrounded by an annular recess (25) with an annular wall (26) positioned in the inner flange surface. A tubular spool core (10) has front surfaces which are connected in a materially bonded manner to the annular wall (26) inside the annular recess (25) of the flange discs (22, 24), wherein at least one channel (32) is provided next to the annular wall (26) inside the annular recess (25) for receiving liquefied connection material. The spool core (10) has approximately the same diameter as the annular wall (26) inside the annular recess (25).

A reel comprises a bottomed circular tube shaped hub that has an outer peripheral face for winding a recording tape around; a first flange that is integrally molded to one end portion of the hub; a second flange that is joined to another end portion of the hub; a plurality of hole portions that are provided at equal intervals on a ring shaped reel gear formed at a lower face of a bottom plate of the hub; and a gate mark that is formed at the bottom plate of the hub, further to a radial direction inside than an inner peripheral face of the hub, wherein a difference in surface roughness between a weld portion and a non-weld portion on the outer peripheral face of the hub is 0.25 m or less.

Proposed is a friction shaft for a slitter that enables a winding pipe to stably roll unit materials formed by cutting a raw material, such as a raw fabric or film, with predetermined intervals, that can fix the rolling pipe even at a low pressure of compressed air, and that has a wide range of available rolling tension because the pressure range of compressed air that can adjust winding torque is wide.

A textile paper yarn package that has a hollow body with opposing open ends, and formed of a paper blank having an outer end edge positioned on an exterior surface of the body and an inner end edge positioned on an interior surface of the body. The outer end edge of the paper blank forms a lap seam that extends in a spiral shape around a predetermined extent of the exterior of the body as it extends between the opposing open ends of the body of the package.

A method for assembling a reel comprising a first flange, a second flange and a barrel is disclosed. This method comprises (i) securing at least one spring-loaded magnetic guide to a base; (ii) positioning the first flange over the at least one spring-loaded magnetic guide and the base, so that a distal end of the at least one spring-loaded magnetic guide is inserted through a first hole in the first flange, (iii) connecting the barrel to the first flange, (iv) connecting the second flange to the barrel so that the barrel is located between the first and second flanges, (v) inserting at least one threaded fastener through a second hole in the second flange such that a distal end of the at least one threaded fastener is magnetically attached to the distal end of the at least one spring-loaded magnetic guide, and (vi) connecting the at least one threaded fastener to the first flange to form the reel. Also disclosed are the structures of the spring loaded magnetic guide.

A method of grooving a durable transfer roll core may comprising loading the durable transfer roll core onto a grooving apparatus and grooving a main surface of the durable transfer roll core via engagement with one or a plurality of cutting tools of the tooling section of the grooving apparatus.
