Abstract: Apparatus for assembling a core for wound sheet material, comprising a tube, a first end member, and a second end member; the apparatus comprising a base, a first chuck for insertion in the first end member, a second chuck for insertion in the second end member, a ram for applying axial pressure such that the first end member is forced into the first end of the tube and the second end member is forced into a second end of the tube, drill devices for drilling fixing apertures, and a monitor device for sensing ambient temperature and enabling the length of the core to be measured at the time of the assembly of the core in the ambient temperature so that the length of the core falls in temperature and length parameters set for subsequent winding of the sheet material on the core.

Abstract: A core for receiving sheet material, which core comprises a tube (2), a first end member (4) which extends into a first end of the tube (2), and a second end member which extends into a second end of the tube (2), and the core being such that the tube is formed of a plurality of part circular tube portions (6) which are connected together along longitudinally extending edges (8), and the first and the second end members are each formed of a plurality of part circular end member portions (10) which are connected together along longitudinally extending edges (12).

Abstract: Apparatus (2) for assembling a core (4) for receiving wound sheet material: which core (4) comprises a tube (6), a first end member (8) inserted in a first end (10) of the tube (6), and a second end member (12) inserted in a second end (14) of the tube (6); and the apparatus (2) comprising a base (16), first chuck means (18) mounted on the base (16) and for insertion in the first end member (8), second chuck means (20) mounted on the base (16) and for insertion in the second end member (12), a ram (22) mounted on the base (16) and for applying axial pressure on one of the first and the second end members (8, 12) such that the first end member (8) is forced into the first end (10) of the tube (6) and the second end member (12) is forced into the second end (14) of the tube (6) thereby to ensure that the first and the second end members (8, 12) are accurately fitted in the tube (6), first drill means (24) for drilling at least one fixing aperture in the first end (10) of the tube (6) and the first end member (8

Abstract: A core (2) for receiving wound sheet material, which core (2) comprises a tube (4), a first end member (6) inserted in a first end (8) of the tube (4), and a second end member (10) inserted in a second end (12) of the tube (4), the core (2) being such that it is able to be earthed in order to enable the discharge of static electricity from the core (2), and the earthing (16) being such that it is effected by a chuck (14) of a machine handling the core (2) during use of the core (2) whereby the static electricity is discharged through the machine.
