Abstract

Abstract An improved cylindrical suction roll suitable for carrying a foraminous screen thereon for forming paper, said cylindrical roll being of the type formed by alternating straight and undulating strips attached to one another and running axially between end members, and the improvement comprising the projection of said straight strips radially beyond said undulating strips to form unitary, circumferentially spaced, continuous axial supports for outer meshed layers. The projecting straight strips are firmly anchored in the honeycomb openwork of the roll by notching the nodes of the undulated strips and applying fillet welds in the notches to create a countersink, or tapered edge, in the area of attachment.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 103 words
In a rotary cylindrical roll of the type comprising a pair of spaced-apart, parallel, circular end members each having an annular peripheral inner face and a plurality of alternate straight strips and bent strips, extending axially between and spaced around, the said annular, inner faces of said members to form a cylindrical openwork, said bent strips each having uniformly spaced, flattened nodes in engagement with straight strips on each side thereof; and means connecting each said node to the adjacent straight strip for mutual support of said strips, the improvement whereby said straight strips extend radially beyond said bent strips, around said roll.
Claim 2
Dependent Claim 103 words
In a rotary cylindrical roll of the type comprising a pair of spaced-apart, parallel, circular end members each having an annular peripheral inner face and a plurality of alternate straight strips and bent strips, extending axially between and spaced around, the said annular, inner faces of said members to form a cylindrical openwork, said bent strips each having uniformly spaced, flattened nodes in engagement with straight strips on each side thereof; and means connecting each said node to the adjacent straight strip for mutual support of said strips, the improvement whereby said straight strips extend radially beyond said bent strips, around said roll.
Claim 3
Dependent Claim 38 words
Apparatus as defined in claim 1 wherein the length of radial extension of said straight strips above said quantitative bent strips is less than the radial distance of said straight strips which is adjacent to said bent strips.
Claim 4
Dependent Claim 22 words
Apparatus as defined in claim 1 wherein circumferentially adjacent ones of said bent strips are oppositely disposed to form a honeycombed-type openwork.
Claim 5
Dependent Claim 48 words
Apparatus as defined in claim 1 wherein a portion of said nodes are cut out from at least the outer edges thereof and said connecting means is a fillet weld partially filling said cutout to form a tapered face, thereby providing an improved fluid flow through the apparatus.
Claim 6
Dependent Claim 80 words
A honeycomb roll of the type having alternate straight and undulated thin strips extending axially from one end of the roll to the other end to define a half hexagonal patterned openwork characterized by each said straight strip extending radially outward substantially beyond the cylindrical plane defined by said undulated strips, and anchoring means, in the said cylindrical plane of said undulated strips, securing said strips to the adjacent portions of said straight strips to form a unitary, integral openwork.
Claim 7
Dependent Claim 80 words
A honeycomb roll of the type having alternate straight and undulated thin strips extending axially from one end of the roll to the other end to define a half hexagonal patterned openwork characterized by each said straight strip extending radially outward substantially beyond the cylindrical plane defined by said undulated strips, and anchoring means, in the said cylindrical plane of said undulated strips, securing said strips to the adjacent portions of said straight strips to form a unitary, integral openwork.
Claim 8
Dependent Claim 32 words
A roll as specified in claim 5, wherein each said straight strip includes a plurality of spaced notches therealong for receiving and supporting the convolutions of circumferentially extending metal tapes, or strips.
Claim 9
Dependent Claim 36 words
A roll as specified in claim 5, plus a hollow cylindrical, foraminous assembly, supported on the outer terminal edge portions of said straight strips, said assembly being adapted to support a Fourdrinier wire trained partially therearound.
Claim 10
Dependent Claim 54 words
A roll as specified in claim 5, wherein said anchoring means comprises a plurality of cutouts, formed in at least the outer edge of each node of said undulates strips, and a fillet weld extending around the periphery of each cutout and securing each said node to the face of the adjacent straight strip.
Claim 11
Dependent Claim 23 words
A roll as specified in claim 8, wherein said fillet weld is beveled to form a sloping, outward-facing edge on each said cutout.
Claim 12
Dependent Claim 173 words
A honeycomb roll of the type having alternate straight and undulated thin strips extending from one end of the roll to the other end to define a half hexagonal patterned openwork, said roll being characterized by an inner said openwork on said roll, said inner openwork having a plurality of said straight strips spaced therearound and extending radially outward substantially beyond the cylindrical plane defined by the said undulated strips thereof; said inner openwork forming a relatively strong, coarse-apertured support; an outer said openwork encircling said inner openwork and supported thereby, said outer openwork having a plurality of said straight strips and undulated strips the said straight strips being spaced therearound and extending radially inward substantially beyond the cylindrical plane defined by the said undulated strips, said outer openwork forming a relatively thin, fine-apertured screen; and means for firmly anchoring the inwardly projecting portions of the said straight strips of said outer openwork to the outwardly projecting portions of said straight strips of said inner openwork to form a unitary composite honeycomb roll.
Claim 13
Dependent Claim 173 words
A honeycomb roll of the type having alternate straight and undulated thin strips extending from one end of the roll to the other end to define a half hexagonal patterned openwork, said roll being characterized by an inner said openwork on said roll, said inner openwork having a plurality of said straight strips spaced therearound and extending radially outward substantially beyond the cylindrical plane defined by the said undulated strips thereof; said inner openwork forming a relatively strong, coarse-apertured support; an outer said openwork encircling said inner openwork and supported thereby, said outer openwork having a plurality of said straight strips and undulated strips the said straight strips being spaced therearound and extending radially inward substantially beyond the cylindrical plane defined by the said undulated strips, said outer openwork forming a relatively thin, fine-apertured screen; and means for firmly anchoring the inwardly projecting portions of the said straight strips of said outer openwork to the outwardly projecting portions of said straight strips of said inner openwork to form a unitary composite honeycomb roll.
