FIELD: textiles, paper.SUBSTANCE: method of sorting strip for feeding to the draw frame with carded spinning system comprises folding of several strips, control of the linear density and stretching with further transition of the strip on the production line. According to the invention, at the stage of transportation of the card sliver from the carding machine to the draw frame the selection of the strip batches is carried out on the database formed from the signals from the sensor of the carding machine, which characterises the average linear density of the strip in each basin, with constant comparison of value of the required linear density of the strip on the draw frame and the total density of the strips, required for its production. The sensor of linear density of the card sliver comprises oppositely located perpendicular to the direction of the strip in the channel, the transmitter and receiver of the optical signal, which outputs are connected to the computing unit. According to the invention the channel for the strip in the sensor housing has a variable diameter which at the inlet of the strip is configured wider with a computing unit located around it, and tapered at the outlet, with a measuring unit located in it, consisting of a transmitter and a receiver, each of which is provided with temperature sensing elements.EFFECT: improving the accuracy of continuous monitoring of the strip linear density on the carding machine, improving the quality of the strip produced on the draw frame.2 cl, 2 dwg |
