Before use, the first pocket is opened by separating the second pocket along the perforation, and placed in a tire let a flow of the particles from inside the first container into the tire through the duct. The tire-valve core is removed from the second container and applied to the wheel.

Tire-balancing system and use thereof

A balancing weight dispenser has a balancing weight storage space for storing a belt of balancing weights on a reel, a belt guide, and a cutter at one end of and/or along a length of the belt guide. The cutter comprises a knife, which is fixedly attached to the balancing weight dispenser. For delivery of a required amount of balancing weight mass, the belt of balancing weights is pulled from the reel until the desired number of balancing weights has been obtained. In the next step, the belt of balancing weights is cut, preferably between two adjacent balancing weights, to separate the selected portion of balancing weights from the remaining belt of balancing weights. The remaining belt falls back to the guide and remains in a desired position for receiving the next portion of balancing weights. This manually operated balancing weight dispenser can be provided at significantly lower costs compared to the automated high performance balancing weight dispensers as known from the prior art. It is very robust and has no serviceable parts.

When the distributor lies on top pressurized gas can be fed into the distributor and the converger is connected to a drainage container. The drainage container is lower than the converter and the distributor.
