Abstract
Abstract A charge or batch of compressible material is first compressed and is then advanced into the interior of a packaging enclosure, such as a package wrapper, while the wrapper is supported in distended condition. The wrapper has an inside dimension smaller than the charge of compressible material to be inserted prior to compression thereof but larger than the compressed charge. After advancement of the compressed charge into the interior of the wrapper, both the wrapper and the charge are delivered from the apparatus at the same rate, and concurrently the compression is released so that the package is completed as the wrapper and charge are being delivered from the apparatus.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
170 words
Apparatus for packaging compressible material comprising spaced guides for holding a tubular package wrapper of substantially uniform cross section in distended or open condition, the guides having delivery ends from which loaded package wrappers are discharged, spaced parallel traveling conveyor devices extended into the space between said guides adjacent the side wall of a distended package wrappeR when positioned on said guides to provide for feed of a compressed charge of material to be packaged into the space within a distended tubular wrapper on said guides, the conveyor devices having entrance end portions adapted to receive a compressed charge of material to be packaged and having delivery ends located adjacent the delivery ends of said guides, means for delivering a package wrapper from the delivery ends of the guides at a predetermined rate, and means for driving the conveyor devices to advance and deliver a compressed package charge at said predetermined rate as the package wrapper is delivered and thereby provide for discharge of a loaded package from the apparatus.
Claim 2
Dependent Claim
170 words
Apparatus for packaging compressible material comprising spaced guides for holding a tubular package wrapper of substantially uniform cross section in distended or open condition, the guides having delivery ends from which loaded package wrappers are discharged, spaced parallel traveling conveyor devices extended into the space between said guides adjacent the side wall of a distended package wrappeR when positioned on said guides to provide for feed of a compressed charge of material to be packaged into the space within a distended tubular wrapper on said guides, the conveyor devices having entrance end portions adapted to receive a compressed charge of material to be packaged and having delivery ends located adjacent the delivery ends of said guides, means for delivering a package wrapper from the delivery ends of the guides at a predetermined rate, and means for driving the conveyor devices to advance and deliver a compressed package charge at said predetermined rate as the package wrapper is delivered and thereby provide for discharge of a loaded package from the apparatus.
Claim 3
Dependent Claim
36 words
Apparatus as defined in claim 1 and further including control means operating in response to advancement of a package charge to actuate the means for delivering a package wrapper from the delivery ends of the guides.
Claim 4
Dependent Claim
40 words
Apparatus as defined in claim 1 and further including conveyor means for successively advancing and delivering charges of compressible material to be packaged to the entrance ends of the conveyor devices and for compressing said charges as they are advanced.
Claim 5
Dependent Claim
135 words
Apparatus for packaging compressible material comprising means for holding a tubular wrapper in distended or open condition comprising spaced guide shoes adapted to be received in the interior of the tubular wrapper, conveyor means between said spaced guide shoes for carrying a compressed package charge into the interior of the distended wrapper and for delivering the compressed charge from the apparatus, and means for delivering the distended wrapper from the apparatus concurrently with delivery of the compressed charge and at the same rate of delivery of the compressed charge and thereby provide for delivery of a loaded package from the apparatus, the means for delivering the distended wrapper comprising a feed roll positioned adjacent the delivery end of one of said guide shoes and having a friction surface engageable with the outside of the wrapper.
Claim 6
Dependent Claim
135 words
Apparatus for packaging compressible material comprising means for holding a tubular wrapper in distended or open condition comprising spaced guide shoes adapted to be received in the interior of the tubular wrapper, conveyor means between said spaced guide shoes for carrying a compressed package charge into the interior of the distended wrapper and for delivering the compressed charge from the apparatus, and means for delivering the distended wrapper from the apparatus concurrently with delivery of the compressed charge and at the same rate of delivery of the compressed charge and thereby provide for delivery of a loaded package from the apparatus, the means for delivering the distended wrapper comprising a feed roll positioned adjacent the delivery end of one of said guide shoes and having a friction surface engageable with the outside of the wrapper.
Claim 7
Dependent Claim
23 words
Apparatus as defined in claim 4 and further including means mounting the wrapper feed roll for movement toward and away from the wrapper.
Claim 8
Dependent Claim
33 words
Apparatus as defined in claim 5 and further including control means operating in response to advancement of a package charge to effect motion of the wrapper feed roll into engagement with the wrapper.
Claim 9
Dependent Claim
130 words
Apparatus for packaging compressible material comprising means for holding a tubular wrapper in distended or open condition, said means comprising spaced guide shoes establishing an angular cross sectional wrapper shape, conveyor means extended into the space between said guide shoes for carrying a radially compressed roll of fibrous insulation into the interior of the distended wrapper, the compressed roll being positioned in the wrapper with the roll axis extended transversely of the wrapper, said conveyor means also providing for delivery of the compressed roll from the apparatus, and means for delivering the distended wrapper from the apparatus concurrently with delivery of the compressed roll and at the same rate as the rate of delivery of the compressed roll and thereby provide for delivery of a loaded package from the apparatus.
Claim 10
Dependent Claim
130 words
Apparatus for packaging compressible material comprising means for holding a tubular wrapper in distended or open condition, said means comprising spaced guide shoes establishing an angular cross sectional wrapper shape, conveyor means extended into the space between said guide shoes for carrying a radially compressed roll of fibrous insulation into the interior of the distended wrapper, the compressed roll being positioned in the wrapper with the roll axis extended transversely of the wrapper, said conveyor means also providing for delivery of the compressed roll from the apparatus, and means for delivering the distended wrapper from the apparatus concurrently with delivery of the compressed roll and at the same rate as the rate of delivery of the compressed roll and thereby provide for delivery of a loaded package from the apparatus.
