Abstract: A stand-alone lug of non-isotropic polymeric or cellulosic material for installation in a recess in a core member of paperboard material for a roll of paper or other sheet material. The lug has a width in the range of from about 0.25 to about 4 inches, a length in the range of from about 0.5 to about 4 inches, and a thickness in the range of from about 0.25 to about 1 inch. The lug also having at least one radially inner surface, the total circumferential width of the inner surface or surfaces being at least about 0.2 inches. The lug may have a recess extending from one end for receiving a key on a stub-chuck. Where the lug is to be used with splined stub-chucks, the lug may have no recess.

Abstract: A tubular core assembly for a roll of paper or other sheet material has a hollow cylindrical core member of metal or plastic material, the core member having at least one lug projecting radially inwardly from an inner surface thereof adjacent to each end of the core member. Each lug is longitudinally spaced from the respective adjacent end of the core member, and an annular plastic end member is located within each opposite end portion of the core member and is a friction fit therein. Each end member has a notch at its longitudinally inner end receiving the lug adjacent to the respective end of the core member to facilitate transmission of torque and axial chuck pressure from the end members to the core member.

Abstract: An annular end member of plastic material for insertion into an end portion of a hollow cylindrical core member of a tubular core assembly for a roll of paper or other sheet material has an outer annular surface securable to an inner annular surface of the core member and an inner annular surface shaped to receive a roll supporting chuck. A radially-projecting lug adjacent an end of the end member is engageable in a lug-receiving notch in the core member, and a plurality of circumferentially-spaced axially-extending channels are provided in the inner annular surface of the end member to receive radially outwardly movable portions of a chuck. The channels have side walls engageable by the radially moveable chuck portions to enable rotational movement of the chuck to be transmitted to the end member. The end member also has a notch for receiving a projection of a roll supporting chuck, the notch extending inwardly from the end of the end member immediately radially inwardly of the lug.

Abstract: A method of mounting narrower paper rolls for unwinding on a pair of stub chucks spaced for mounting and unwinding full width paper rolls and carried by arms of a pair of multiple reel stands includes providing a narrower paper roll wound on a tubular core assembly having a hollow cylindrical core member and an annular end member of metal or plastic within each opposite end portion of the core member. The end members are removed from the core member, and the core member is mounted at a desired longitudinal location on a full length shaft having opposite ends engageable with the stub chucks. Core member engaging devices are provided to enable the core member to be secured in the desired longitudinal location and to transmit rotational torque from the shaft to the core member. The full length shaft with the narrower paper roll thereon is then mounted on the stub chucks.

Abstract: An annular end member of plastic material for insertion into an end portion of a hollow cylindrical core member of a tubular core assembly for a roll of paper or other sheet material has an outer annular surface securable to an inner annular surface of the core member and an inner annular surface shaped to receive a roll supporting chuck. A radially-projecting lug adjacent an end of the end member is engageable in a lug-receiving notch in the core member, and a plurality of circumferentially-spaced axially-extending channels are provided in the inner annular surface of the end member to receive radially outwardly movable portions of a chuck. The channels have side walls engageable by the radially moveable chuck portions to enable rotational movement of the chuck to be transmitted to the end member. The end member can be constructed so as to be a universal fit on various different types of chuck.

Abstract: A tubular core assembly for a roll of paper or other sheet material has a hollow cylindrical core member formed of paperboard material, and an annular end member of metal or plastic material within each opposite end portion of the core member. Each end member has an outer annular surface secured to the inner annular surface of the core member and an inner annular surface shaped to receive a roll supporting chuck. Each end member also has a pair of radially-projecting lugs at diametrically opposite positions at the respective end of the tubular core assembly, the core member has a pair of lug-receiving notches at diametrically opposite positions at each end receiving the lugs of the respective end member to facilitate transmission of torque and axial chuck pressure from the end member to the core member.

Abstract: A packaged roll of paper or other sheet material has a protective sheet of material wrapped around the circumference of the roll with overlapping longitudinally-extending edge portions secured together. The said protective sheet extends beyond the roll at opposite ends to provide projecting protective sheet portions which are crimped radially inwardly over the outer annular portions of the ends of the roll and a header assembly is located internally of the crimped over projecting protective sheet portion at at least one end of the roll.

Abstract: A tubular core assembly for a roll of paper or other sheet material has a hollow cylindrical core member formed by multiple wraps of paperboard material. An annular collar is located within each opposite end portion of the core member, each collar being a rigid body of non-isotropic material and having an outer annular surface secured to the inner annular surface of the core member and an inner annular surface shaped to receive a roll supporting chuck. The ratio of collar wall thickness to core member wall thickness is in the range of from about 1.3:1 to about 2:1.

An annular end member of metal or plastic material has a sleeve portion within the collar at each end of the tubular core assembly, the sleeve portion having an outer annular surface secured to the inner annular surface of the collar and an inner annular surface shaped to receive a roll supporting chuck.

Abstract: A non-returnable newsprint carrier system is provided which is adapted for winding or newsprint, shipping and storing of newsprint and mounting in reels of offset printing presses on stub shafts, and which is characterized by eliminating the need for a return to the newsprint manufacturer, increasing core crush resistance during shipping and storing, and reducing roll vibration during unwinding in the printing press. The system comprises a tubular core without metal end caps thereon and defining inside surfaces at opposite ends for receiving therewithin the reel stub shafts of the offset printing press. Core plugs are provided for being inserted into the ends of the tubular core to prevent damage to the end portions of the tubular core and to the newsprint roll. Each of the core plugs comprise a solid body without holes or grooves therein and formed of crush resistant material.

Abstract: A packaged roll of paper or other sheet material includes a roll of paper or other sheet material, a protective sheet of material wrapped around the circumference of the roll and having overlapping longitudinally-extending edge portions secured together. The protective sheet extends beyond the roll at opposite ends thereof to provide projecting protective sheet portions, and the projecting portion of the protective sheet at each end is crimped radially inwardly over the outer annular portion of the end of the roll. At least one header assembly at each end of the roll is located externally and/or internally of the crimped over projecting protective sheet portion, and at least one header assembly has a series of generally rectangular strips of material superposed one on top of the other in a star-like manner with central portions overlapping and secured together and shorter edges outermost and adjacent but within the periphery of the roll.
