Claims

[Claims for Utility Model Registration] Fitted and supported by a bobbin wheel, the bobbin is rotated by engaging with a bobbin locking portion formed on its outer circumferential surface, and is attached to the outer circumference for fixing the end of the roving when starting to wind the thread. In the bobbin for the roving frame with the parts attached,
The locking member is provided so that its upper edge is at a height that approximately coincides with the vertical center of the pretusa battledore when the machine is restarted with the bobbin in a normally fitted state, and its width W is set such that the upper edge of the locking member has a height that substantially coincides with the vertical center of the pretusa battledore when the machine is restarted when the bobbin is properly fitted. The height of the part is h
, when Wo is the width of the fastening member necessary to reliably attach the roving thread when the machine is restarted when the bobbin is properly fitted to the bobbin wheel, 30mm≧W≧Wo+h. Bobbin for spinning machines.
