Rubber Balers
A bailing apparatus may include a multi-component bolster assemblies that may ease installation and removal, reduce wear and tear and maintenance, and/or improve baling efficiency by reducing material waste, imperfections, and/or contamination. The bolster assemblies may include a plurality of coupling portions that engage a hydraulic rod and may enable the bolster assembly to self-center within a press chamber during normal baling operations. The bolster assemblies also may include an island portion that may be attached to the coupling portions and to a bolster cap, and the latter may be attached using retainer bolts having substantially planar heads that may define lips that run about frustums. The bolts may substantially planar head may reduce irregularities in the bale and the lips may prevent material seepage into the bolster assemblies.
Process for producing wet rubber masterbatch, wet rubber masterbatch, and rubber composition containing wet rubber masterbatch
A method for producing a wet rubber masterbatch uses a single-screw extruder. The single-screw extruder includes a screw, and an external cylinder in which a slit extended along the length direction of the external cylinder (the screw-shaft direction) is formed in an internal wall surface of the external cylinder, and when the width of the slit is represented by A and the clearance between a crest of the screw and the internal wall surface of the external cylinder is represented by B, the following expression (1) is satisfied:
0<AB(Y)/AB(X)<0.9(1)
wherein AB (Y) is the product of A and B at a downstream side along the screw-shaft direction of the external cylinder, and AB (X) is the product of A and B at an upstream side along the screw-shaft direction of the external cylinder.

Friable bales
A process to make a friable bale, and a friable bale formed from the same, wherein the friable bale is formed from a composition comprising coated polymer particles, which comprise polymer particles formed from a polymer composition comprising an olefin-based polymer, and a coating formed from a coating composition comprising an aqueous metal acid dispersion, and an aqueous polysiloxane emulsion, and wherein the friable bale has a compression force ?1.00 MPa.

Rubber bales and apparatus and method for making same
Improved bales may be formed using methods that include baling equipment with multi-component bolster assemblies that may ease installation and removal, reduce wear and tear and maintenance, and/or improve efficiency by reducing material waste, imperfections, and/or contamination. The bolster assemblies may include a plurality of coupling portions that engage a hydraulic rod and may enable the bolster assembly to self-center within a press chamber during normal baling operations. The bolster assemblies also may include an island portion that may be attached to the coupling portions and to a bolster cap, and the latter may be attached using retainer bolts having substantially flat, non-circular heads. The bolts may reduce irregularities in the bale and/or prevent material seepage into the bolster assemblies. During maintenance, an operator may remove only the bolster cap island assembly for cleaning, substantially reducing the time and strength needed to clean and/or repair the baler and reduce downtime.
