Abstract: The invention pertains to a rider roll unit for winding machines with at least one support or carrier drum for winding web-like material to be woundwith at least one rider roll (1) rotatably mounted to a tie-bar (2) for placing the roll (12) to be wound under a load, as a function of its diameterwith pivotably mounted arms (3) to support the tie-bar (2) andwith a drive (9) for pivoting the support arms (3) as a function of the change in diameter of the roll (12) to be wound.

Abstract: A device for reeling web-like material, in which the roll being formed is held between heads borne on carrier arms, which device reels the roll with a central drive. The drive is provided by direct-current, permanent magnet electric motors maximum power output mounted in the carrier arms, in which motors the stator, is faced with permanent magnets made of samarium cobaltate (SmCo.sub.5).

Abstract: A web threading apparatus for a web slitting machine which longitudinally divides a wide web in a slitting or cutting station, including a threading device having a threading rod guided by chains through the machine. The threading device supplies first and second groups of sub-webs to first and second groups of associated winding apparatus.

Abstract: This invention pertains to web-slitting machines having automatic feed of empty roll cores to each winding station. The cores are inserted as a set from one side of the machine into troughs provided on separate feed beams located above the support roller or rollers on which rewinding takes place. Sequential cores are supported alternately by first and second troughs so that the cores are laterally offset, but still overlapped in radial cross section. The feed beams with troughs are pivotably mounted to move from above and between first and second sets of winding stations to a location near the winding stations where clamping pins from support arms are brought into engagement with the cores, for securing the cores for final positioning to commence winding.
