Abstract

A flyer for spinning a fibrous roving onto a bobbin includes a housing defines a central hole passing therethrough. A center rod, supporting the bobbin, is rotated by a spinning system. A battery is contained in the flyer and powers an electric motor. A hollow level wind frame is affixed to the housing and defines an elongated slot passing therethrough. A level wind gear in the level wind frame is rotated by the electric motor. A level wind carriage system is driven by the level wind gear and oscillates repeatedly between a first end and a second end as the level wind gear is rotated, and includes a pawl engaged with the level wind gear. A guide is coupled to the pawl and passes through the elongated slot defined by the level wind frame. The fibrous roving passes through the guide.

Claims6

Dependent claims

A flyer for spinning a fibrous roving onto a bobbin and configured for use with a spinning system, comprising:

(a) a housing defining a central hole passing therethrough;
(b) a center rod that passes through the housing and that is configured to be rotated by the spinning system, the center rod supporting the bobbin, the center rod defining a passage that opens to a center hole that is in alignment with the central hole of the housing so that the fibrous roving passes into the center rod through the passage and out through the central hole of the housing;
(c) a balance rod extending from a first end of the housing parallel to the center rod, at least one battery disposed inside of the balance rod;
and
(d) a level wind carriage system including:
(i) a hollow level wind frame extending from a second end of the housing, opposite from the first end, that is parallel to the center rod, the hollow level wind frame defining an elongated slot passing therethrough,
(ii) an electric motor disposed within the hollow level wind frame adjacent to the housing, the electric motor powered by the at least one battery;
(iii) a bi-directional worm gear that is disposed inside the hollow level wind frame, the bi-directional worm gear in alignment with the electric motor and coupled directly thereto so as to be rotated directly by the electric motor;
(iv) a pawl that is engaged with the bi-directional worm gear so as to oscillate between a first end of the bi-directional worm gear and an opposite second end of the bi-directional worm gear repeatedly as the bi-directional worm gear is rotated by the electric motor;
and
(v) a guide that is coupled to the pawl and that passes through the elongated slot defined by the level wind frame, through which the fibrous roving passes to the bobbin.
