Abstract

A bale press for compressing a bale of compressible material such as cotton is described. The bale press includes a base frame structure and a pair of platens which have generally rectangular bale compressing faces for compressing a cotton bale to facilitate the bale tieing operation. The platens are carried by the base frame structure so that they may be moved relatively toward a compression zone to compress a cotton bale sufficiently to enable the bale tie wires to be applied. A plurality of elongated, wedge-shaped, bale compression members are provided on at least one of the platens. These bale compression members protrude outwardly from the platen where they are mounted to provide a compression area which is sufficiently small so that the cotton bale is compressed only in close proximity to the positions where a single bale tie is to be placed. A sufficient number of bale compression members are provided to facilitate the application of the ties required for the bale. Through the use of such bale compression members, the overall horsepower required to operate the bale press may be significantly reduced.

Dependent claims

A bale press for compressing a bale of compressible material having opposed outer surfaces by forcing said outer surfaces toward one another to reduce the dimensions of the bale and thereby facilitate securing of the bale with bale ties, said bale press comprising:

a base frame structure;
first and second platens, each provided with a respective generally rectangular bale compressing face having a length and a width and an area which is essentially coextensive in dimensional size with an area of a respective one of said surfaces,
said platens being carried by said base frame structure with said faces thereof disposed in substantial parallelism, in spaced apart facing relationship, and in substantial alignment to present a bale compression zone therebetween, said platens being mounted on said base frame structure for relative movement of said faces toward one another to reduce a dimension of said zone;
a plurality of elongated, wedge-shaped, bale compression members, said wedge-shaped members each having a longitudinal dimension, a lateral dimension and a thickness, said wedge-shaped members being mounted on at least one of said platens with the longitudinal dimensions thereof extending across the width of the face of the platen on which the members are respectively mounted and with the lateral dimensions thereof extending outwardly away from the face of the platen on which the members are respectively mounted and toward the compression zone, each said member thereby presenting a longitudinally extending distal compression edge spaced from the face of the respective platen, the thickness of each member at the distal edge thereof being sufficiently small to compress a cotton bale only in close proximity to a position where a single bale tie is to be placed;
wherein said at least one of said platens is provided with a series of slots which extend across the width of the face thereof, said bale compression members each having a longitudinally extending base edge which is oriented as a lateral extension of the bale compression member relative to said distal compression edge thereof, said bale compression members being mounted on said at least one of said platens with said base edges received in respective slots;
and
a drive mechanism that is mechanically coupled to at least one of said platens and operable to move the platens relatively toward one another.

A bale compression member for use in a bale press for compressing a bale of compressible material having opposed outer surfaces by forcing said outer surfaces toward one another to reduce the dimensions of the bale and thereby facilitate securing of the bale with bale ties, said bale press comprising a base frame structure and first and second platens, each said platen being provided with a respective generally rectangular bale compressing face having a length and a width and an area which is essentially coextensive in dimensional size with an area of a respective one of said surfaces, said platens being carried by said base frame structure with said faces thereof disposed in substantial parallelism, in spaced apart facing relationship, and in substantial alignment to present a bale compression zone therebetween, said platens being mounted on said base frame structure for relative movement of said faces toward one another to reduce a dimension of said zone, said press further including a drive mechanism that is mechanically coupled to at least one of said platens and operable to move the platens relatively toward one-another,

said bale compression member being characterized by having a longitudinal dimension, a lateral dimension and a thickness, and being configured and adapted for inserting into a slot in at least one of said platens with the longitudinal dimension thereof extending across the width of the face of the platen on which the member is to be mounted, and with the lateral dimension thereof extending outwardly away from the face of the platen on which the member is to be mounted and toward the compression zone, said member thereby presenting a longitudinally extending distal compression edge spaced from the face of the respective platen, the thickness of the member at the distal edge thereof being sufficiently small to compress a bale only in close proximity to a position where a single bale tie is to be placed.
