Apparatus for conveying travelable body
First Claim
1. A device for conveying travelable bodies provided with:
- a fixed path allowing a string of travelable bodies to freely travel thereon with a front edge of one travelable body always kept in contact with a rear edge of another travelable body;
means to transmit traveling power to said travelable bodies;
said means to transmit traveling power to said travelable bodies comprising means for subjecting one side of each of said travelable bodies to friction drive and back-up means for subjecting the other side of each of said travelable bodies to pressure at a point opposite said friction drive,and means for applying braking power to both sides of to said travelable bodies; and
said means to transmit traveling power to said travelable bodies and said means for applying braking power to said travelable bodies being disposed in a manner such that, when a leading one of said travelable bodies comes to have both its sides pressed laterally by said means for applying braking power to said travelable bodies, a rearmost one of said travelable bodies comes to have both its sides pressed laterally by said means to transmit traveling power to said travelable bodies.

Abstract
The invention relates to a device for conveying travelable bodies which are provided no driving source, on a fixed path. A plurality of travelable bodies can travel on the fixed path while aligned substantially in close contact with each other. Traveling power is transmitted to one of a plurality of travelable bodies which is positioned on at least one end of the alignment. The traveling power drives the travelable body with frictional force while pressing one side surface of the travelable body, and is transmitted to the travelable body while backing up the other side surface of the travelable body. A device to transmit traveling power is arranged on only a part of the fixed path.
