Abstract
A belt module having a grid geometry including cavities and ribs associated with an outer surface for attaching a high friction material.
Claims45
A belt module for use in a modular conveyor belt comprising:
- a) A body having an outer surface and an oppositely disposed inner surface;
- b) A plurality of cavities in the body, each cavity extending from an opening in the outer surface towards the inner surface, the cavity openings being arranged in spaced relation on the outer surface;
- c) A plurality of ribs fixed to the body, each rib being disposed so that it extends across several of the plurality of openings;
- d) Each of the ribs having an inner surface portion facing generally in the direction of the body inner surface, a pair of substantially oppositely facing side surface portions extending from the rib inner surface portion, and an outer surface portion between the rib side surface portions and facing generally opposite to the rib inner surface portion;
- and
- e) Resilient material on the outer surface of the body to provide a frictional article transporting surface on the module, the resilient material extending into each cavity and engaging the rib associated with that cavity by contacting at least the rib inner surface portion to retain the resilient material on the body.

A belt module for use in a modular conveyor belt comprising:
- a) A body having an outer surface and an oppositely disposed inner surface;
- b) At least one cavity in the body extending from an opening in the outer surface toward the inner surface;
- c) At least one rib fixed to the body and extending in a direction across the cavity in a manner leaving portions of the opening and the cavity unobstructed adjacent opposite sides of the rib, the rib having an inner surface portion disposed toward the inner surface of the body;
- d) Resilient material on the outer surface of the body to provide a frictional article transporting surface on the module, the resilient material extending into the cavity on opposite sides of the rib and engaging at least the inner surface portion of the rib to retain the resilient material on the body.

A method for making a belt module for use in a modular conveyor belt comprising:
- a) Providing a body having an outer side surface and an oppositely disposed inner side surface, link ends on opposite ends of the body, at least one cavity extending from an opening in the outer surface towards the inner surface, and at least one rib on the body and extending in a direction across the cavity in a manner leaving portions of the opening and the cavity unobstructed adjacent opposite surfaces of the rib;
- and
- b) Molding thermoplastic material on the body so that the material provides a frictional article transporting surface on the outer surface of the body and so that the material extends into the cavity and extends about the rib to retain the material on the body.
