Rack (textile industry)
The stretch bench or lantern bench was used in the textile industry for the pre-spinning of the card sliver made of cotton . The card sliver produced by the carding machines essentially ran through a first stretching stage between weight-loaded rollers , in order to then be fed into high cans (sheet metal containers), which in turn rotated around their own longitudinal axis. The jugs were initially cylindrical in shape, later conical like lanterns, hence the name lantern bank.
The rack was applied for a patent in 1775 by the Englishman Richard Arkwright .
The result of this production step was a yarn-like material that, however, did not yet have any tensile strength . Only the final production step with a spinning machine like on a waterframe , a spinning mule or a self-actuator created a tear-resistant thread for further processing with a loom .
The rack was later supplemented by another invention by Richard Arkwright: the track . Today the distance alone is enough to produce an intermediate product from a card sliver, which can be processed on a ring or rotor spinning machine.
