Abstract
In the manufacture of a cable-type tire chain having elongate flexible side members and cross-members carrying traction sleeves, the cross-members are connected to the side members by hooks which are crimped to the side members in a press. To assemble the cross members and side members, they are supported in an assembly jig, with the hooks attached to the opposite ends of the cross-members and embracing the side members. The hooks on one side of the chain are crimped simultaneously to the relevant side member in a single pressing operation while supported in the jig, which applies tension to the side member.
