Abstract
A device for introducing yarn into a pneumatic yarn texturizing means, in which the yarn is positioned across the inlet orifice of the texturizing means, a stream of fluid is forced against the yarn to introduce it into the orifice in the form of a loop and a yarn cutting device, located downstream of the orifice in the direction of movement of the yarn, is actuated, its operation being synchronized with that of the fluid stream.
Claims4
An apparatus for introducing at least one yarn into a pneumatic yarn texturizing means, said apparatus comprising:
- an orifice for introducing yarn into the texturizing means;
- a fluid nozzle fixed in spaced relation opposite said orifice;
- means for positioning the yarn to extend across and between the orifice and fluid nozzle;
- means for supplying liquid under high pressure to said fluid nozzle whereby said liquid pushes said yarn into said orifice after the liquid escapes the nozzle;
- yarn cutting means for cutting the yarn, said yarn cutting means being located downstream of the orifice in the direction of yarn extent across the orifice;
- means for synchronizing the operation of the liquid supply means with the yarn cutting means;
- and
- means for mounting the fluid nozzle and cutting device so as to be moved from juxtaposition with the orifice after the yarn is introduced through the orifice and into the texturizing device so as to allow texturizing to take place under usual conditions.
