Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
174 words
A cloth folding apparatus comprising a folding table, a folding machine supported on said table for longitudinal displacement thereon and including a carrier device for holding a first roll of cloth to be wound-off by the machine in an operative position in the course of travel thereof, said carrier device including bearings having upwardly open grooves for receiving the cloth roll, a cloth roll magazine secured to said machine for movement therewith and including support means for receiving at least one further roll of cloth whereby said further roll travels with the folding machine along said table, said magazine including endless conveyor means on which said support means is mounted, and means for moving the conveyor means to transport the support means therewith, said conveyor means being positioned on said machine relative to said carrier device to transport said support means along a curved path proximate said bearings of the carrier device to deposit said further roll into the grooves in said carrier device after removal of the first said roll of cloth therefrom.
Claim 2
Dependent Claim
174 words
A cloth folding apparatus comprising a folding table, a folding machine supported on said table for longitudinal displacement thereon and including a carrier device for holding a first roll of cloth to be wound-off by the machine in an operative position in the course of travel thereof, said carrier device including bearings having upwardly open grooves for receiving the cloth roll, a cloth roll magazine secured to said machine for movement therewith and including support means for receiving at least one further roll of cloth whereby said further roll travels with the folding machine along said table, said magazine including endless conveyor means on which said support means is mounted, and means for moving the conveyor means to transport the support means therewith, said conveyor means being positioned on said machine relative to said carrier device to transport said support means along a curved path proximate said bearings of the carrier device to deposit said further roll into the grooves in said carrier device after removal of the first said roll of cloth therefrom.
Claim 3
Dependent Claim
16 words
A machine as claimed in claim 1 wherein said conveyor means comprises a longitudinally displaceable conveyor.
Claim 4
Dependent Claim
59 words
A machine as claimed in claim 2 wherein the cloth rolls have equal widths, said conveyor comprising two strands which are transversely spaced over a distance somewhat exceeding the width of a cloth roll, and two pairs of rotatable conveyor wheels supporting said strands and driving the same, said support means being mounted in opposition on the respective chains.
Claim 5
Dependent Claim
52 words
A machine as claimed in claim 3 wherein said support means are secured to said strands and are provided with open notches which are oriented to engage the further cloth roll and transport the same over one of the pairs of conveyor wheels for deposit into the grooves in said carrier device.
Claim 6
Dependent Claim
47 words
A machine as claimed in claim 4 wherein said one pair of conveyor wheels has an axis parallel to said further cloth roll and arranged closely adjacent the carrier device, said strands traveling along said cruved path as they pass on said one pair of conveyor wheels.
Claim 7
Dependent Claim
23 words
A machine as claimed in claim 4 wherein said support means comprises U-shaped plates secured to the conveyor, said plates defining said notches.
Claim 8
Dependent Claim
