Abstract
Abstract A horizontal baler for baling paper products incorporating a horizontally disposed gathering and compression chamber having an open upper portion communicating with a hopper wherein the paper to be compressed is directly introduced into the hopper and a gatherer and compression ram transfers the paper into a compression chamber to form a parcel of layered compressed material. The paper may be continuously introduced into the hopper as the gatherer ram cycles and a cover plate on the ram receives the paper when the ram is extended, wiping the paper from the cover plate as the ram retracts. Cycling of the gatherer ram continues until a parcel of predetermined compression is achieved, whereupon an ejector or transfer ram perpendicularly disposed to the gatherer ram intermittently transfers the compressed parcel in the direction of the formed compressed parcel layers through automatic strapping apparatus which straps the parcel in a direction perpendicular to the formed layers to define a bale. Gathering, compressing and transferring occurs at substantially the same horizontal orientation, and automatic control means are utilized to permit automatic operation of the apparatus cycle.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
170 words
The method of compressing, forming and strapping a bale of flexible, resilient material, such as paper products, comprising the steps of compressing the material in a compression zone in a first given direction to form a compressed parcel having layers transversely oriented to said first given direction, maintaining said parcel under compression in said zone and intermittently translating the compressed parcel in a second direction substantially parAllel to said layers thereof and transverse to said first given direction, the extent of movement of said parcel in said second direction during each cycle of movement being substantially less than the length of the parcel in said second direction, exteriorly strapping the parcel in a direction transverse to the direction of orientation of the parcel layers intermediate cycles of movement of said parcel in said second direction, the compression of the parcel being of a maximum extent prior to translating the parcel in said second direction, and partially releasing the pressure on the parcel while in the compression zone prior to strapping.
Claim 2
Independent Claim
170 words
The method of compressing, forming and strapping a bale of flexible, resilient material, such as paper products, comprising the steps of compressing the material in a compression zone in a first given direction to form a compressed parcel having layers transversely oriented to said first given direction, maintaining said parcel under compression in said zone and intermittently translating the compressed parcel in a second direction substantially parAllel to said layers thereof and transverse to said first given direction, the extent of movement of said parcel in said second direction during each cycle of movement being substantially less than the length of the parcel in said second direction, exteriorly strapping the parcel in a direction transverse to the direction of orientation of the parcel layers intermediate cycles of movement of said parcel in said second direction, the compression of the parcel being of a maximum extent prior to translating the parcel in said second direction, and partially releasing the pressure on the parcel while in the compression zone prior to strapping.
Claim 3
Independent Claim
189 words
The method of compressing, forming and strapping a bale of flexible, resilient material, such as paper products, comprising the steps of compressing material in a compression zone in a first given direction to form a compressed parcel having layers transversly oreinted to said first given direction, maintaining said pracel under compression in said zone and intermittently translating the compressed parcel in a second direction substantially parallel to said layers thereof and transverse to said first given direction, the extent of movement of said parcel in said second direction during each cycle of movement being substantially less than the length of the parcel in said second direction, exteriorly strapping the parcel in a direction transverse to the direction of orientation of the parcel layers intermediate cycles of movement of said parcel in said second direction, the parcel being first compressed in the compression zone to a maximum extent prior to translating the parcel in said second direction, and then partially releasing the compression on the parcel in the compression zone prior to strapping by permitting said parcel to expand in a direction counter to said first direction a predetermined amount.
Claim 4
