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.
Claims3
In apparatus for winding cross-wound coils with a constant thread feeding velocity having a reciprocating thread guide, means for reciprocating the thread guide and means for driving the reciprocating means for time intervals alternatingly with at least two different speeds, a device for irregularizing or disturbing the winding pattern in the apparatus comprising separate means for driving the thread guide and for winding the cross-wound coil, means for controlling both said thread guide driving means and said cross-wound coil winding means in dependence upon one another, so that the quotient of the peripheral speed of the cross-wound coil and the cosine of half the thread crossing angle is constant, both said driving means and said winding means being each selectively switchable from one to another speed of rotation differing by approximately 10% from one another in accordance with a parameter of switching selections that includes rhythmic switching and random switching at predetermined time intervals, and gear transmission systems including respective shifting clutches operatively connected to each of said thread-guide driving means and said cross-wound coil winding means, and timing control means for controlling shifting of said shifting clutches.
In apparatus for winding cross-wound coils with a constant thread feeding velocity having a reciprocating thread guide, means for reciprocating the thread guide and means for driving the reciprocating means for time intervals alternatingly with at least two different speeds, a device for irregularizing or disturbing the winding pattern in the apparatus comprising separate means for driving the thread guide and for winding the cross-wound coil, means for controlling both said thread-guide driving means and said cross-wound coil winding means in dependence upon one another, 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 a planetary gear transmission system serving as a superimposed transmission system operatively connected to said cross-wound coil winding means.
In apparatus for winding cross-wound coils with a constant thread feeding velocity having a reciprocating thread guide, means for reciprocating the thread guide and means for driving the reciprocating means for time intervals alternatively with at least two different speeds, a device for irregularizing or disturbing the winding pattern in the apparatus comprising separate means for driving the thread guide and for winding the cross-wound coil, means for controlling both said thread-guide driving means and said cross-wound coil winding means in dependence upon one another, 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 planetary gear transmission systems drivable dependently upon one another operatively connected to said thread-guide driving means and said cross-wound coil winding means, respectively, at least one of said planetary gear transmission systems serving as a superimposed transmission system.
