METHOD FOR OBTAINING A CONSTANT JOINING MATERIAL IN AIR VORTEX SPINNING PROCESSES

摘要

The invention relates to a method for starting a drawing frame (1) used for drawing a fiber bond (2). Said drawing frame (1) comprises at least one pair of forward rollers (3) and a pair of rear rollers (4) that is provided with a clamping line (5), one end (6) of a fiber bond being provided for starting the drawing frame (1). According to the invention, said end (6) of the fiber band enters the clamping line (5) of the pair of rear rollers (4) during starting of the drawing frame (1) only once the acceleration response process in the rotary speed curve of the pair of forward rollers (3) and in the rotary speed curve of the pair of rear rollers (4) has been completed.
