Abstract

A repair, conversion or retrofit kit includes at least two continuously closable replacement baler belts which correspond substantially in their combined width to the width of a continuously closed baler belt to be replaced. The replacement baler belts may be closable in a force-fitting and/or form-fitting manner by a connecting means, and the connecting means may be at least partially hook connectors. In some embodiments, the repair, conversion or retrofit kit further includes at least one guide means arranged on the round baler such that at least two replacement baler belts each extend laterally with respect to the at least one guide means, and the at least two replacement baler belts are guided laterally with respect to one another. In some cases, the guide means is an auxiliary guide disk arranged on a rotatable shaft of the round baler.

First claim

We claim:

1. A repair, conversion or retrofit kit for a round baler, the kit comprising at least two closable replacement baler belts which correspond in their combined width to the width of a baler belt to be replaced;
wherein the at least two replacement baler belts are closable in a force-fitting or form-fitting manner, at least partially, by hook connectors;
wherein the repair, conversion or retrofit kit further comprises at least one auxiliary guide disk configured in a split manner such that it may be fastened to a rotatable shaft of the round baler by placing the at least one auxiliary guide disk around the rotatable shaft;
wherein the at least one auxiliary guide disk is configured as two half-disks;
wherein the at least one auxiliary guide disk is fastened to the rotatable shaft between a central guide disk of the rotatable shaft and either a left-hand guide disk of the rotatable shaft or a right-hand guide disk of the rotatable shaft;
wherein the at least one auxiliary guide disk is fastened to the rotatable shaft between opposing edges of two of the at least two replacement baler belts;
wherein the at least two closable replacement baler belts are connectable without cold vulcanization, and wherein full tensile loading is immediately available after closing of the at least two closable replacement baler belts; and,
wherein, when the kit is installed on the round baler, the round baler has the at least two replacement baler belts and an original baler belt, and wherein the at least two replacement baler belts correspond in their joint width to the width of the original baler belt.

2. The repair, conversion or retrofit kit according to claim 1 , wherein the at least two replacement baler belts have the same width.

3. The repair, conversion or retrofit kit according to claim 1 further comprising screws, clamps, split pins, or wire for fastening the at least one auxiliary guide disk to the rotatable shaft.

4. The repair, conversion or retrofit kit according to claim 1 wherein the at least two closable replacement baler belts and the at least one auxiliary guide disk are arranged on the round baler such that the at least two closable replacement baler belts each extend laterally with respect to the at least one auxiliary guide disk, and wherein the at least two closable replacement baler belts are guided laterally with respect to one another.
