  • Method and apparatus for separating the roving wound on packages from the flyers of a roving frame or the like, and for securing the roving end to the packages before doffing
    Patent number: 5524428
    Abstract: To secure the end of the roving (5) to packages (9) before their doffing from a roving frame, it is proposed to initially raise the package support carriage (2) into a position such that the lower end (4a) of the tubes (4) is at the level of the compressor (16) of the flyers (6), then rotate the packages (9) and flyers (6) through a few revolutions in order to wind and secure the roving (5) onto the lower end portion (4a) of the tubes (4), after which the carriage (2) is lowered to break the roving (5) in the section between the lower end (4a) of the tubes (4) and the flyers (6). Preferably, before lowering the packages (9), a reserve of roving (5) is created by slowly rotating the flyers (6) and packages (9) through a few revolutions, to simultaneously twist the roving (5) and strengthen it.
