摘要： Apparatus for reeling or winding light grades of paper webs such as tissue. A reed drum having a pair of parallel-spaced horizontal rails extending from the delivery end portion of the reel drum, winds the web onto a spool. Primary transfer arms at each end of the reed drum transfer the spool downwardly along the periphery of the drum onto the rails. The spool is supported at its opposite ends on cam tracks pivoted about axis parallel to the axis of the reel drum. Air cylinders are connected with the cam tracks to position the cam tracks to hold the spool out of engagement with the periphery of the drum and pivot the tracks to engage the spool with the drum with a preselected minimum nip pressure. The tracks have incoming curvilinear portions formed about one axis and dropping off at their outgoing ends, to lower the partially wound spool onto the rails. The air cylinders cooperate with the outgoing portions of the cam tracks to provide a uniform minimum nip pressure between the spool and reel drum as the spool advances along the outgoing curvilinear portions of the cam tracks. The partially wound spool is delivered from the cam tracks onto the rails, along which the reeling operation is continued under the control of secondary transfer arms.

摘要： A winder rider roll assembly for paper rolling devices is provided with a rider roll having a counter weighting system in which chains affixed adjacent axial ends of the rider roll assembly are entrained over chain sprockets non-rotatably affixed to a cross shaft mechanism with one sprocket for each chain being affixed to one piece of a two piece cross shaft with the cross shaft pieces being torsionally connected through a variable spring rate coupling employing selectively inflatable air bags for transmission of torsional forces. Also disclosed is a method of controlling the level and force of the rider roll by varying air pressure in the air bags of the variable spring rate coupling.

摘要： Apparatus and method for starting respective leading ends on web running continuously and wound into successive rolls. As each roll reaches a final diameter, a fresh leading end is provided on the web by machine direction slitting partial separation of a leading end tongue area and cross machine slitting of the remainder of a fresh leading end on the web, followed by complete separation of a leading end on the tongue area and directing of the tongue area and the remainder of the fresh leading end of the web into winding relation onto a fresh rotary core for winding of the web into another roll. This is adapted to be effected automatically and without interruption of high speed web travel and roll winding.

摘要： A calender and method of operating the same, where the calender has a vertical stack of a plurality of rotary rolls, each of the rolls having bearing structure at each opposite end provided with a thrust shoulder cooperative with a stop shoulder on a respective suspension spindle at each end of the rolls. There are guideways for the bearing structures, and there is an arrangement for vertically shifting the rolls between a lowered mode for spaced apart independent suspension by stop shoulders and a raised nipping mode relation with one another. The weight of the bearing structures of the rolls in the raised nipping mode relation is relieved as by cooperating pawl and rack structure.

摘要： Apparatus and method for starting respective leading ends on web running continuously and wound into successive rolls, such as paper. As each roll reaches a final diameter, a fresh leading end is provided on the web by slitting (32, 33) in a generally cross-machine direction from a leading starter tongue projection extending downstream. The starter tongue projection with the fresh leading end of the web is directed into winding relation onto a fresh rotary core (17) for winding of the web into another roll. This is adapted to be effected automatically and without interruption of high speed web travel and roll winding.

摘要： For use in a papermaking machine or paper converting mechanism having an arrangement for winding a roll of paper onto a core at high speed, an expanding core chuck for insertion into a roll core which includes a spindle mounted for rotation within a housing, a cone mounted on the spindle and having camming surfaces thereon, a piston reciprocable axially of the spindle, means for introducing hydrostatic pressure to one end of the piston, a cup secured to the opposite end of the piston and having a plurality of radially deflectable leaves in spaced relation therearound. The leaves have angular surfaces thereon engageable by the camming surfaces on the core. When the angular surfaces are contacted by the camming surfaces of the core due to movement of the piston, the leaves are deflected outwardly into tight fitting relationship within the interior of the roll core,
