Abstract
Abstract An apparatus for automatically transporting at least one can between a sliver delivering spinning industry machine, e.g. a carding machine, and a sliver fed spinning industry machine, e.g. a drawing frame, by means of a transporting carriage. In order to improve loading and unloading as well as transport of the spinning cans, the carriage control, the carding machine control device and the drawing frame control device are connected with a central control unit.

Claim 1
Independent Claim
150 words
An apparatus for automatically transporting at least one can between a sliver furnishing spinning industry machine and a sliver fed spinning industry machine, comprising: a transporting carriage operatively associated with said sliver furnishing and sliver fed machines for transporting the can between said machines; first electronic control means connected to said carriage for controlling its operation; second electronic control means connected to said sliver furnishing machine and to said sliver fed machine for controlling the operation of said machines and for receiving from at least one of said machines condition signals indicative of the operating state of said one machine; and a central control unit connected to said first and second control means for receiving the condition signals from said second control means and for supplying control signals to said first electronic control means for controlling the transport of the can between said machines in dependence on the condition signals.
