PURPOSE:To suppress the abrasion of a flocked belt while preventing the failure in the start of the removing of residual roving, by switching a driving power applied to a mobile frame in the forward driving of a flocked belt in such a manner as to be smaller in the final stage of the stroke than in the initial stage. CONSTITUTION:A flocked belt 12 is placed on a mobile frame 20 and a switching point is set to a point before the mobile frame 20 reaches the limit of forward motion. Air supplied to an air cylinder 31 is switched from high- pressure air to low-pressure air between the switching point and the forward limit to switch the driving power of the forward motion of the mobile frame 20 to a smaller level. |
