A stock delivery system is provided having a rectangular sectioned distributor of substantially square section connected in stock supplying relation to a headbox having an apertured distributor place, a mixing chamber receiving stock therein connecting by way of a throttle plate to a multi-tier diffuser section comprising cylindrical tubes that diverge to a square section. A parallel flow section of predetermined length connects to a tapered nozzle section. The structural elements of the apparatus, including the support beam, a portion of the diffuser section, and the roof section are connected in liquid transfer relation to permit the passage of liquid a controlled temperature therethrough. Also, the slice is provided with liquid containment capability, and also includes a segmented extension chamber to permit substantially unrestricted later expansion or contraction of the slice under changing thermal conditions.

Stock supply system for paper machine

A paper slitter machine having a plurality of slitter heads in mutually spaced apart relation located across the width of the machine, each slitter head having a slitter disc operable in cooperating relation with a respective annular disc or slitter band mounted for rotation on a shaft, for the slitting of a paper web into discrete width portions on passage of the web past the slitter heads, is provided with a plurality of slitter indexing means mounted on traverse means for retraction to a position clear of the machine, the slitter indexing means having a slitter stop for each slitter head, the stops being adjustable upon the traverse means to permit pre-indexing of each of the stops to a desired predetermined position along the length of the traverse means such that, with the traverse means repositioned within the slitter machine and having the stops positioned in an operative position, each of the slitter heads may then be brought rapidly into indexed relation with the respective pre-set stop, whereby the slitter machine may be re-indexed with a minimum of down time. The indexing of the slitter machine is generally achieved in this arrangement by moving each of the annular slitter band discs into abutting relation with the respective pre-set stop, and thereafter bringing the respective disc into operative relation with the respective indexed slitter band disc.

Slitter indexing system

A calendar stack is provided with pneumatic actuators of the expansible bag or bellows type wherein a selected roll has the end bearings thereof carried by a pair of pivoted control arms, the position of a respective control arm being selectively controlled, for upward loading or for downward loading of the stack by a single primary actuator. The selected direction of force application by the primary actuator is determined by a force transmission linkage shiftable by a secondary actuator between a first and a second position, for roll upward loading or roll downward loading.
