This rubber friction wheel sits on the end of the bobbin winding device and engages with the machine's handwheel. As the handwheel turns, friction from the rubber tire causes the bobbin shaft to rotate, winding the thread onto the bobbin.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMaintenance Indicator:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eOver time, these tires can become old, grey, brittle, or dry-rotted, causing them to slip or crack.
