Abstract
Abstract A device for continuously loading strip-form material onto a substantially horizontally disposed conveying surface of a dryer or the like comprises an upstanding chute having strip-form material deposited thereinto in overlapping longitudinally pleated layers, means forming an arcuately extending shaft receiving layers from the chute with opposite edges of the layers abutting radially spaced, arcuately shaped inner and outer wall portions defining the shaft, and transfer means directing layers of the strip-form material to a substantially horizontally disposed conveying surface. A drum or wheel member having a cylindrical peripheral surface forms the shaft inner wall and is rotated to impart a desired circumferential velocity thereto, and an arcuately extending run or path of a continuous conveyor belt forms the radially spaced outer wall and is driven in a manner to impart a circumferential velocity thereto in excess of that of the inner wall, thereby turning or flipping the overlapped layers of the strip-form material so that leading layers overlap or overlie adjacent trailing layers as the material is transferred onto the conveying surface.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
232 words
A device for continuously loading strip-form material onto a horizontally disposed conveying surface, comprising: means forming a main continuous conveyor belt having a concave, arcuate run; means forming a rotatably disposed member overlying said arcuate conveyor run and having a substantially cylindrical peripheral surface confronting, and radially inwardly spaced from, said arcuate run to define an arcuately extending shaft having radially spaced inner and outer wall portions respectively defined by said outer cylindrical surface and a confronting surface of said conveyor passing through said arcuate run; means for feeding and guiding at least one continuous strip of material into an inlet end of said arcuate shaft in overlapping layers extending transversely of said conveyor belt; drive means rotating said cylindrical surface in one angular direction and propelling said continuous conveyor belt in an opposite angular direction and at a velocity so that said conveyor moves through said arcuate run at a circumferential velocity exceeding a circumferential velocity of said cylindrical surface for advancing overlapped layers of the strip of material through the arcuately extending shaft; transfer means receiving layers of the strip material from said arcuate shaft and delivering the same to a substantially horizontally disposed conveying surface, whereby the material will be deposited onto the horizontal conveying surface with leading ones of the layers overlapping adjacent trailing layers, thereby enabling tangle-free removal of the strip material from the horizontal conveying surface.
Claim 2
Independent Claim
232 words
A device for continuously loading strip-form material onto a horizontally disposed conveying surface, comprising: means forming a main continuous conveyor belt having a concave, arcuate run; means forming a rotatably disposed member overlying said arcuate conveyor run and having a substantially cylindrical peripheral surface confronting, and radially inwardly spaced from, said arcuate run to define an arcuately extending shaft having radially spaced inner and outer wall portions respectively defined by said outer cylindrical surface and a confronting surface of said conveyor passing through said arcuate run; means for feeding and guiding at least one continuous strip of material into an inlet end of said arcuate shaft in overlapping layers extending transversely of said conveyor belt; drive means rotating said cylindrical surface in one angular direction and propelling said continuous conveyor belt in an opposite angular direction and at a velocity so that said conveyor moves through said arcuate run at a circumferential velocity exceeding a circumferential velocity of said cylindrical surface for advancing overlapped layers of the strip of material through the arcuately extending shaft; transfer means receiving layers of the strip material from said arcuate shaft and delivering the same to a substantially horizontally disposed conveying surface, whereby the material will be deposited onto the horizontal conveying surface with leading ones of the layers overlapping adjacent trailing layers, thereby enabling tangle-free removal of the strip material from the horizontal conveying surface.
Claim 3
Dependent Claim
47 words
A device as claimed in claim 1, and further characterized by said drive means rotating said cylindrical surface at one angular velocity and propelling said conveyor so that said conveyor moves through said arcuate run at an angular velocity equal to that of said rotating, cylindrical surface.
Claim 4
Dependent Claim
169 words
A device as defined in claim 1, and further characterized by said feeding and guiding means comprising: a substantially horizontally disposed continuous belt conveyor having an inlet end and a discharge end for feeding strip-form material in a flat disposition longitudinally therealong from the inlet end to the discharge end; means mounting the inlet end of said conveyor for pivotal movement about a vertically disposed axis; means forming a guide trough receiving strip material from said feeding conveyor and directing the material downwardly toward said arcuately extending shaft; means forming a carriage disposed for oscillatory movement transversely of said main continuous conveyor belt and supporting said guide trough and the discharge end of said conveyor for movement therewith; means forming an upstanding chute receiving strip material from said guide trough and directing the same to said arcuately extending shaft; and drive means oscillating said carriage transversely of said main conveyor belt to deposit the strip material in said chute in overlapping layers extending transversely of said main conveyor belt.
Claim 5
Dependent Claim
56 words
A device as defined in claim 3, and further characterized by said upstanding chute comprising: a substantially vertical, descending run of said main conveyor belt extending from said guide trough to said arcuately extending run; and a substantially vertically disposed plate member spaced from said vertical run and disposed substantially tangentially of said rotating cylindrical surface.
Claim 6
Dependent Claim
45 words
A device as defined in claim 1, and further characterized by said transfer means including a rising run of the main conveyor belt extending tangentially from said arcuately extending run and terminating at a point substantially level with a longitudinal axis of said cylindrical surface.
Claim 7
Dependent Claim
30 words
A device as defined in claim 1, and further characterized by said arcuately extending run of said main conveyor having an angular extent greater than 90* but not exceeding 180*.
Claim 8
Dependent Claim
116 words
A device as defined in claim 1 and further characterized by said rotatably disposed member comprising: a pair of axis-parallel, laterally spaced idlers engaging said main conveyor belt in a manner to define said arcuately extendinG run; an inner series of arcuately shaped sections extending between and mounted on, said pair of idlers and circumferentially spaced therearound at common radial distances from an axis thereof; and an outer series of arcuately shaped sections extending between, and mounted on, said pair of idlers and circumferentially spaced therearound at slightly greater common radial distances than said inner series and having circumferentially opposite end portions overlapping end portions of adjacent ones of said inner series of arcuately shaped sections.
Claim 9
Dependent Claim
40 words
A device as defined in claim 7 and further characterized by means for adjustably moving said inner series and said outer series of arcuately shaped sections radially of said idlers to vary a radial width of said arcuately extending shaft.
