Abstract
Method of irregularizing or disturbing the winding pattern in apparatus for winding cross-wound coils with a constant thread feeding velocity having a reciprocating thread guide which is driven for time intervals alternatingly with at least two different speeds, which includes driving a cross-wound coil in synchronism with and dependent upon the motion of the thread guide so that the quotient of the peripheral speed of the cross-wound coil and the cosine of half the thread crossing angle is constant; and device for carrying out the method.
