DEFINITION

Classification: 242/FOR.145

Foreign Art Collections for bobbin-winding machines in which the thread layer or guide has a quick traverse movement relative and longitudinal to the bobbin or in which the bobbin is reciprocated relatively to the thread guide, so as to lay the thread on the bobbin in crossing spirals, producing a cross or crisscross wind. In this subclass the number of convolutions, coils, or spirals varies somewhat in the different layers, usually decreasing in number toward the periphery.
