  • Bobbin-changing device with automatic means for severing the thread or strip
    Patent number: 4085900
    Abstract: A bobbin-changing device for a textile winding machine in which an elongate thread or strip of textile fibres such as spun yarn, sliver or roving is wound on successive bobbins, the device being for replacing a fully wound bobbin with an empty bobbin and including means for allowing the fully wound bobbin to drop down from its winding position and a frictional member which is engaged by the periphery of the fully wound bobbin at a position roughly diametrically opposed to the position at which the thread or strip reaches the periphery of the fully wound bobbin as the bobbin drops down from its winding position, for accelerating in the wind-on direction the position at which the thread or strip reaches the periphery of the fully wound bobbin and thereby breaking the thread or strip.
