Abstract: A controlled deflection roll for use in calenders and like machines has a non-rotatable carrier for a hollow cylindrical shell the end portions of which are rotatable on bearings and the central portion of which surrounds hydraulically operated shell deforming elements. A first hydraulic circuit is provided to supply heated oil to the deforming elements, and a second hydraulic circuit serves to feed lubricant to the bearings. The two circuits are separated from each other by thermal barriers which are installed between the shell and the carrier intermediate the deforming elements and the bearings. Valves and/or flow restrictors are provided in the second circuit to vary the rate of feed of lubricant to and/or the flow of lubricant from the bearings. This renders it possible to establish a desired temperature profile along the full length of the peripheral surface of the shell.

Abstract: A die member for joining a fastener to a panel includes a generally rectangular opening defined by two spaced apart opposed end walls, which receive the end walls of a pilot portion of a fastener. The end walls of the opening terminate into arcuate corners and are adapted to sheer and deform the pilot end walls of the fastener thereby forming bearing panel support abutments capable of providing a liquid tight seal between the panel and the fastener. The die member also includes clinching lips on opposed sides of the die opening. The clinching lips preferably include a top portion and tapered wall which deform the panel edges into grooved openings in the fastener thereby providing a liquid tight seal. The die opening is surrounded by a generally planar surface having an outer generally rectangular perimeter having generally arcuate corners. The generally arcuate corners form arcuate depressions within the panel when the die member operates on the fastener to attach it to the panel.

Abstract: A roll, specifically a paper machine press roll, with a hollow rotatable roll body features a roll shell and on at least one of its two ends a hollow roll journal.

Abstract: A pressurizing roller for use in a laminator to bond a film to a panel has a hollow outer shell and flanges on both ends. A roller shaft extending through the flanges and the outer shell transfers its angular moment of force via bearings directly to the flanges and via the flanges to the outer shell to provide uniform distribution of pressure by the roller outer shell to the film and panel. The outer shell is heated to a uniform temperature throughout.

Abstract: A method of forming a tachometer roller for a tape drive assembly for detecting the speed of a tape moving along a reference axis when the tape is in contact with the roller. The roller includes a cylinder extending in a longitudinal axis and adapted to be fixed in a tape drive assembly for rotation along the reference axis. The periphery of the cylinder defines an air vent groove running obliquely to the longitudinal axis for venting of air captured between the periphery and the tape. The vent groove terminates in respective circumferential grooves formed in respective edge portions of the roller. The vent groove is formed from a single plunge cut of a tool starting at a first circumferential groove and terminating at the other circumferential groove.

Abstract: A self-loading type of controlled deflection roll includes, in a preferred embodiment, a pivot assembly which is pivotally mounted to a support shaft near either end of the roll. The roll includes a roll shell having an extension attached to either end which extends co-axially outwardly from the roll shell. These axial extensions of the roll shell are supported by non-self-aligned bearings on the pivot assemblies near either end of the roll. Intermediate the end of the roll shell and the bearings is a heat barrier which prevents hot hydraulic fluid within the interior of the roll from contacting or heating the bearings which rotatably support the roll shell about the self-loading assembly. The bearings can, therefore, be provided with a lubricant which is sealed and shielded from the temperature of the hydraulic fluid within the roll.

Abstract: A deflection controlled roll has a rotatable shell supported on a non-rotating central beam by a plurality of individual shoes which are positioned transversely of the beam between the beam and the shell. A curved semicylindrical surface of the shoe bears against an inside surface of the shell and is hydrodynamically lubricated by an oil film, in the nature of a plain bearing. The shoes are biased by inflatable air lift bellows which are positioned within recesses within the shoe, between the shoe and the beam. The shoes are mounted on the beam on pins which provide at least three degrees of freedom of movement. An improved drive for the roll shell has a cog belt sheave mounted on the shell in concentric relation to one of the shell support bearings. A cog-type drive belt is threaded on the sheave, and a drive pulley for the drive belt is positioned normal to the direction of shell deflection such that the deflections do not change the spacing between the pulley and the sheave.

Abstract: A roller for compressing of webs of material comprises a rotating hollow roller traversed lengthwise by a stationary crosshead. Hydraulic loading devices in the form of sealing members act on the inside circumference of the hollow roller and delimit hydrostatic bearing pockets to which hydraulic pressure fluid can be supplied. The extension of the sealing members is limited by head bolts, which make it possible to position the hollow roller relative to the crosshead during operation.
