Improved balers may include a traveling chute that may reduce wear and tear and maintenance, and/or improve efficiency by reducing downtime. The traveling chute may include moving guides that include channels that engage tongues of stationary guide rails disposed on a baler. For example, the channels may be substantially rectangular channels that run the length of the moving guide. Similarly, the stationary guides may include substantially rectangular tongues and the moving guides may slide across the tongues and upper surfaces of the stationary guides as the traveling chute moves between various positions. The moving guides may include polyoxymethylene inserts in which the channels may be provided. The moving guides and stationary guides may be provided as a kit for attachment to various baling apparatuses. Additional features and components also are described.

In the field of tire production, the invention relates to methods and systems for creating unvulcanized rubber batches prior to mixing them in a rubber mixer, including selecting at least one batch for mixing in the mixer, wherein each batch corresponds to a selection of rubber bales (A.sub.I, B.sub.I, C.sub.I) each corresponding to a rubber nature (A, B, C) having predefined characteristics, in order to obtain a proportion corresponding to a predetermined proportion, a target weight to attain a difference between (a) the required weight of the batch and (b) the sum of the weight of the bales (A.sub.I, B.sub.I, C.sub.I) and the weight of the pieces (A.sub.IJ, B.sub.IJ, C.sub.IJ).
