Abstract
The method and apparatus of controlling moving fabric weight per unit length in strips made up of different pieces which comprises predetermining the desired absolute weight per unit length of the finished fabric; predicting accurately the absolute weight per unit length of the moving finished fabric; determining any error difference in the absolute weights, recognizing the beginning and end of each piece of fabric; adjusting the input feed rate according to the error difference between the desired weight of the finished fabric and the predetermined finished weight; determining that a new piece of fabric has reached the exit site of a primary feed station; predicting accurately the weight of a new piece of pre-finished material and comparing this weight with the stored weight of pre-finished material of the prior piece to determine the percentage difference in weight of the prior piece in the formative zone or tenter to the new piece that will subsequently reach the infeed station to the tenter; and controlling the motor speed feeding the fabric to the tenter to produce the predetermined absolute weight per unit length in the finished fabric.
