PCT No. PCT/EP94/00527 Sec. 371 Date Nov. 9, 1995 Sec. 102(e) Date Nov. 9, 1995 PCT Filed Feb. 24, 1994 PCT Pub. No. WO94/20659 PCT Pub. Date Sep. 15, 1994An apparatus and process for positioning a transport carriage that supports a cloth or yarn roller in front of a weaving machine. The apparatus is provided with two non-contact sensors that are attached to spaced apart locations on the transport carriage. The transport carriage is further provided with two selectively actuatable steerable wheels. After the transport carriage is initially positioned in front of the weaving machine distance measurements are made between the non-contact sensors and fixed reference points on the weaving machine. Based on these distance measurements the wheels integral with the transport carriage are selectively actuated in order to place the transport carriage in parallel alignment with the weaving machine. |
