Abstract
Abstract A wood chip product and a process for baling wood chips in which sufficient compressive pressure is applied to a quantity of wood chips to substantially reduce its volume, and force the water liquid from the chips to create, without any binder, an adhered but separable compact mass of chips. The mass is enclosed in a flexible web cover, retained by spaced, circumferential ties which extend in the direction of compression. The chips are thus reduced to from one-half to one-sixth of their bulk or volume and have lost from about 15% to about 40% of their weight.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
73 words
A wood chip product suitable for producing paper pulp comprising a quantity of green, naturally moist wood chips in a compressed condition generally perpendicular to the general planes of said chips and having the fibres of adjacent chips intermeshed, said fibres retaining their integrity, said quantity of wood chips occupying from approximately one-half to approximately one-sixth its normal volume and having a substantially reduced quantity from its normal amount of clear liquid, therein.
Claim 2
Dependent Claim
73 words
A wood chip product suitable for producing paper pulp comprising a quantity of green, naturally moist wood chips in a compressed condition generally perpendicular to the general planes of said chips and having the fibres of adjacent chips intermeshed, said fibres retaining their integrity, said quantity of wood chips occupying from approximately one-half to approximately one-sixth its normal volume and having a substantially reduced quantity from its normal amount of clear liquid, therein.
Claim 3
Dependent Claim
23 words
A green naturally moist wood chip product consisting essentially of compressed wood chips from which a portion of its water has been exuded.
Claim 4
Dependent Claim
23 words
A green naturally moist wood chip product consisting essentially of compressed wood chips from which a portion of its water has been exuded.
