Abstract
Abstract A carpet roll machine having a pair of drivable rollers arranged to define a supporting nip on which a roll of carpet can be formed. A lower deflector between the rollers and in sliding contact with at least one of them selectively presents an upwardly facing slide surface. An upper deflector is moveable between a first position wherein it is disposed above the lower deflector and a rest position remote from the first position. In the first position the upper deflector presents a downwardly facing slide surface which together with the slide surface of the lower deflector and the adjacent rollers define a cylindrical space into which the end of a piece of carpet can be fed and constrained to follow a cylindrical path to form an incipient roll. The lower deflector is pivotable between positions wherein it contacts one or the other of the rollers enabling a pile-in or pile-out roll to be formed. A gate is provided upstream of the lower deflector to direct the feed end to one or the other side of the lower deflector.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
243 words
A carpet rolling machine comprising a pair of rotatably drivable roll supporting rollers disposed to define a supporting nip on which a roll of carpet can be formed, a lower deflector disposed between the rollers, means for mounting said lower deflector for movement into sliding contact with each of the rollers selectively, said lower deflector having an upwardly facing cam surface, an upper deflector selectively movable from a rest position to an operative position disposed above the lower deflector, said upper deflector having a downwardly facing cam surface, said cam surfaces of said upper and lower deflectors and the periphery of the adjacent rollers together defining a generally cylindrical space to which an end of a piece of carpet can be fed and constrained to follow a cylindrical path when said upper deflector is in said operative position, means for moving said lower deflector into contact with a selected first of the rollers, means for rotating said first roller in a direction such that the surface of said first roller in contact with the lower deflector moves downwardly, means rotating the second roller in a direction relative to said first roller such that the surface of said second roller adjacent to said first roller moves upwardly, and means for feeding and directing the end of said piece of carpet upwardly against the upwardly moving surface of said second roller to feed said carpet into said cylindrical space to form an incipient carpet roll.
Claim 2
Dependent Claim
243 words
A carpet rolling machine comprising a pair of rotatably drivable roll supporting rollers disposed to define a supporting nip on which a roll of carpet can be formed, a lower deflector disposed between the rollers, means for mounting said lower deflector for movement into sliding contact with each of the rollers selectively, said lower deflector having an upwardly facing cam surface, an upper deflector selectively movable from a rest position to an operative position disposed above the lower deflector, said upper deflector having a downwardly facing cam surface, said cam surfaces of said upper and lower deflectors and the periphery of the adjacent rollers together defining a generally cylindrical space to which an end of a piece of carpet can be fed and constrained to follow a cylindrical path when said upper deflector is in said operative position, means for moving said lower deflector into contact with a selected first of the rollers, means for rotating said first roller in a direction such that the surface of said first roller in contact with the lower deflector moves downwardly, means rotating the second roller in a direction relative to said first roller such that the surface of said second roller adjacent to said first roller moves upwardly, and means for feeding and directing the end of said piece of carpet upwardly against the upwardly moving surface of said second roller to feed said carpet into said cylindrical space to form an incipient carpet roll.
Claim 3
Dependent Claim
31 words
A carpet rolling machine as recited in claim 1, including means for wiping a formed carpet roll from said supporting rollers after removal of said upper deflector to the rest position.
Claim 4
Dependent Claim
40 words
A carpet rolling machine as recited in claim 1, wherein said means for mounting said lower deflector comprises means for pivotably supporting said lower deflector for movement between said roll supporting rollers, and power means for pivoting said lower deflector.
Claim 5
Dependent Claim
27 words
A carpet rolling machine as recited in claim 1, wherein said cam surface of each of said upper deflector and said lower deflector is an arcuate surface.
Claim 6
Dependent Claim
111 words
A carpet rolling machine as recited in claim 1, wherein said means for feeding and directing the end of said carpet upwardly comprises a ramp deflector, a feed roller disposed intermediate and selectively defining a feed nip between said ramp deflector and one of said supporting rollers, a gate deflector, means for feeding said end of said carpet over said gate deflector, means for moving said gate deflector selectively for directing said carpet either ov .id feed roller to one of said feed nips or under said feed roller to the other of said feed nips, and means for rotating said feed roller in the opposite direction to said support rollers.
Claim 7
Dependent Claim
45 words
A carpet rolling machine as recited in claim 5, including pivot means for mounting said gate deflector for pivotable movement relatively to said ramp deflector, and said means for moving said gate deflector comprises power means for pivoting said gate deflector about said pivot means.
Claim 8
Dependent Claim
66 words
A carpet rolling machine as recited in claim 5, wherein said feed roller is mounted for bodily movement to close the feed nip defined between the feed roller and said one supporting roller when the carpet is fed over said feed roller and to close the feed nip defined between the feed roller and the ramp deflector when the carpet is fed below said feed roller.
Claim 9
Dependent Claim
94 words
A carpet rolling machine as recited in claim 7, wherein said means for feeding and directing said carpet further comprises a second feed roller disposed downstream from said ramp deflector relative to said gate deflector, said second feed roller having a periphery disposed for intersecting carpet fed over said ramp deflector when said carpet is fed below the first mentioned feed roller, and means for rotating said second feed roller in a direction opposite to the first mentioned feed roller when carpet is fed between said ramp deflector and said first mentioned feed roller.
Claim 10
Dependent Claim
94 words
A carpet rolling machine as recited in claim 5, wherein said means for feeding and directing said carpet further comprises a second feed roller disposed downstream from said ramp deflector relative to said gate deflector, said second feed roller having a periphery disposed for intersecting carpet fed over said ramp deflector when said carpet is fed below the first mentioned feed roller, and means for rotating said second feed roller in a direction opposite to the first mentioned feed roller when carpet is fed between said ramp deflector and said first mentioned feed roller.
Claim 11
Dependent Claim
55 words
A carpet rolling machine as recited in claim 9 or 5, wherein said means for feeding and directing said carpet includes a second ramp deflector intermediate said second feed roller and the other of said supporting rollers for directing carpet from said second feed roller toward and against the periphery of said other supporting roller.
