Abstract

A rubber continuous annular baler press belt is made of at least one of rubber and rubber-like materials. The press belt includes an embedded core of a reinforcing fabric and has at least two individual superimposed fabric layers ( 6, 7, 8 ). The ends of each fabric layer mutually abut and do not overlap each other at the abutment location. The abutment locations ( 11, 13, 15 ) are arranged over the periphery of the press belt so as to be offset from each other.

First claim

What is claimed is:

1. A continuous annular baler press belt made of at least one rubber material comprising:
an inner rubber cover sheet and an outer rubber cover sheet;
an embedded core of reinforcing fabric arranged between said inner and outer rubber cover sheets;
said embedded core having first, second and third individual fabric layers skimmed with bonding rubber and being arranged one atop the other to define a carcass;
said first individual fabric layer being next to said inner rubber cover sheet and said third individual fabric layer being next to said outer rubber cover sheet;
said second individual fabric layer being sandwiched between said first and third individual fabric layers;
each of said fabric layers having two ends;
said two ends of each fabric layer mutually abutting at an abutment location so as not to overlap;
the continuous annular baler press belt defining a periphery;
the abutment locations of said individual fabric layers being completely separate from each other and being arranged distributed over said periphery of the press belt;
said individual fabric layers being made of different types of fabric;
said abutment locations of said three fabric layers being arranged offset at 120° with respect to one another over said periphery of the continuous annular baler press belt;
a first covering strip interposed between said first individual fabric layer and said inner rubber covering sheet so as to cover only the abutment location of said first individual fabric layer;
a second covering strip interposed between said third individual fabric layer and said outer rubber covering sheet so as to cover only the abutment location of said third individual fabric layer; and,
the abutment location of said second individual fabric layer being disposed directly between said first and said third individual fabric layers so as to cause said first and third individual fabric layers to conjointly define a covering therefor.

2. The continuous annular baler press belt of claim 1 , wherein said individual fabric layers made of different types of fabric have different mechanical characteristics.

3. The continuous annular baler press belt of claim 1 , wherein said individual fabric layers made of different types of fabric are made of different fabric materials.
