Abstract

An apparatus includes a receiving module, a conversion module, first and second rollers, a motor, and a cutting head. The receiving module receives a desired weight value. The conversion module converts the desired weight value to a first length of wheel weight material based on a linear density of the wheel weight material. The first and second rollers engage first and second opposing sides of a continuous strip of the wheel weight material. The linear density of the wheel weight material is approximately constant along the continuous strip. The motor directly drives the first roller based on the first length. The cutting head is selectively actuated to cut the wheel weight material.

Claims13

Dependent claims

An apparatus comprising:

at least one module configured to (i) receive a desired weight value to correct an imbalance of a wheel/tire assembly and (ii) convert the desired weight value to a corresponding weight amount of a wheel weight material;
a roller configured to engage a first side of the wheel weight material;
a contact surface configured to engage an opposite side of the wheel weight material from the roller;
a forcing element configured to press the wheel weight material between the roller and the contact surface;
a motor that drives the roller according to the weight amount;
a marking device that selectively adds a mark to a piece of the wheel weight material corresponding to the weight amount;
and
a cutting apparatus that is selectively actuated to separate the piece from the wheel weight material.
