Claim 1

Independent Claim 159 words

Apparatus for applying a color pattern to the raised nap of a flocked sheet (10) comprising: A. an engraved roll (60) having recesses (92) therein; B. a drum roll (47) spaced parallel to said engraved roll so that the sheet can advance between said rolls; C. means (48, 63) for rotating said rolls in unison; D. means (66) for applying dye to said engraved roll so as to fill the recesses therein; and E. means for critically adjusting the spacing between said rolls so that the flock fibers (14c) on the sheet positioned opposite said engraved roll; 1. just protrude into the opposite recesses therein, and 2. take on dye when under substantially no applied pressure by combined dipping and wicking action, said adjusting means including, a. a pair of stiff, resilient beams (50) supporting the opposite ends of said drum roll, and b. means (53) for bending said beams so as to ease the rolls toward one another.

Claim 2

Dependent Claim 159 words

Apparatus for applying a color pattern to the raised nap of a flocked sheet (10) comprising: A. an engraved roll (60) having recesses (92) therein; B. a drum roll (47) spaced parallel to said engraved roll so that the sheet can advance between said rolls; C. means (48, 63) for rotating said rolls in unison; D. means (66) for applying dye to said engraved roll so as to fill the recesses therein; and E. means for critically adjusting the spacing between said rolls so that the flock fibers (14c) on the sheet positioned opposite said engraved roll; 1. just protrude into the opposite recesses therein, and 2. take on dye when under substantially no applied pressure by combined dipping and wicking action, said adjusting means including, a. a pair of stiff, resilient beams (50) supporting the opposite ends of said drum roll, and b. means (53) for bending said beams so as to ease the rolls toward one another.

Claim 3

Dependent Claim 52 words

take on dye when under substantially no applied pressure by combined dipping and wicking action, said adjusting means including, a. a pair of stiff, resilient beams (50) supporting the opposite ends of said drum roll, and b. means (53) for bending said beams so as to ease the rolls toward one another.

Claim 4

Dependent Claim 52 words

take on dye when under substantially no applied pressure by combined dipping and wicking action, said adjusting means including, a. a pair of stiff, resilient beams (50) supporting the opposite ends of said drum roll, and b. means (53) for bending said beams so as to ease the rolls toward one another.

Claim 5

Dependent Claim 11 words

Apparatus as defined in claim 1 wherein: A. said drum roll;

Claim 6

Dependent Claim 42 words

has a multiplicity of passages therein, and B. further including means (55, 56) for connecting the interior of said drum roll to a source of pressure below atmospheric so that a vacuum is created at said passages for holding the flocked sheet.

Claim 7

Dependent Claim 42 words

has a multiplicity of passages therein, and B. further including means (55, 56) for connecting the interior of said drum roll to a source of pressure below atmospheric so that a vacuum is created at said passages for holding the flocked sheet.

Claim 8

Dependent Claim 16 words

Apparatus as defined in claim 2 wherein the surface (47a) of said drum roll is textured.

Claim 9

Dependent Claim 35 words

Apparatus as defined in claim 2 and further including a plate (57) spaced slightly from the surface portion of said drum roll unengaged by the sheet so as to block selected ones of said passages.

Claim 10

Dependent Claim 59 words

Apparatus as defined in claim 1 and further including additional engraved rolls (61, 62) spaced parallel to said drum roll, all of said engraved rolls being arranged with respect to said beams so that adjustment of said beams through a small angle produces substantially equal changes in the spacings between said drum roll and all of said engraved rolls.

Claim 11

Dependent Claim 31 words

Apparatus as defined in claim 1 and further including means (54, 56, 47a, 42, 43) for inhibiting relative movement between said drum roll and the flocked sheet engaging around said roll.

Claim 12

Dependent Claim 27 words

Apparatus as defined in claim 1 and further including means (43) for increasing the width of the flocked sheet prior to its engagement around said drum roll.

Claim 13

Dependent Claim 196 words

Apparatus for applying a color pattern to the raised nap of a flocked sheet (10) comprising: A. at least one rotary engraved roll (60) having recesses (92) therein for containing a viscous dye during rotation of the rolls; B. a rotary drum roll (47) spaced parallel to said engraved rolls so that the sheet can advance between said drum roll and said engraved rolls, dye (88) contained in said recesses, said dye being sufficiently viscous to remain in said recesses during rotation of said engraved rolls; C. means (48, 63) for rotating said rolls in unison; and D. means (50,53) for adjusting said drum roll toward said engraved rolls so that the flock fibers (14c) on the sheet engaging over said drum roll which are positioned opposite the dye filled recesses in said engraved rolls are dipped into said dye under substantially no pressure, while said fibers not opposite said dye filled recesses are deflected by said engraved rolls, said adjusting means including: a. a pair of stiff, resilient beams (50) supporting the opposite ends of said drum roll, and b. means (53) for bending said beams so as to ease the rolls toward one another.

Claim 14

Dependent Claim 196 words

Apparatus for applying a color pattern to the raised nap of a flocked sheet (10) comprising: A. at least one rotary engraved roll (60) having recesses (92) therein for containing a viscous dye during rotation of the rolls; B. a rotary drum roll (47) spaced parallel to said engraved rolls so that the sheet can advance between said drum roll and said engraved rolls, dye (88) contained in said recesses, said dye being sufficiently viscous to remain in said recesses during rotation of said engraved rolls; C. means (48, 63) for rotating said rolls in unison; and D. means (50,53) for adjusting said drum roll toward said engraved rolls so that the flock fibers (14c) on the sheet engaging over said drum roll which are positioned opposite the dye filled recesses in said engraved rolls are dipped into said dye under substantially no pressure, while said fibers not opposite said dye filled recesses are deflected by said engraved rolls, said adjusting means including: a. a pair of stiff, resilient beams (50) supporting the opposite ends of said drum roll, and b. means (53) for bending said beams so as to ease the rolls toward one another.

Claim 15

Dependent Claim 26 words

Apparatus as defined in claim 8 when said drum roll is made of aluminum; and has a hard roughened surface (47a) for engaging the flocked sheet.

Claim 16

Dependent Claim 55 words

An apparatus as defined in claim 8 wherein said drum roll is hollow, and contains a multiplicity of passages (54) connecting the interior of said drum roll and its surface, and means (56) for drawing a vacuum in said drum roll so that the flocked sheet engaging over said drum roll tends to cling thereto.

Claim 17

Dependent Claim 31 words

Apparatus as defined in claim 10 and further including means (57) spaced from a surface portion of said drum roll unengaged by the sheet for blocking selected ones of said passages.
