ABSTRACT:
An apparatus for preventing an unwinding of a roving end from a full package roving bobbin during the transportation thereof. This apparatus is constructed in combination with the transportation mechanism formed in the known doffing mechanism or known overhead roving bobbin transportation system, in a condition such that a part of the constitutional mechanical elements of such known transportation mechanisms are utilized as a part of the constitutional mechanical elements of the apparatus according to the present invention. In the apparatus of the present invention, a pressing member is utilized for applying pressure against the peripheral face of the winding portion of each roving bobbin while this bobbin is rotating, and therefore the free end of the roving is firmly attached to the above-mentioned peripheral face of the roving bobbin. Consequently, any possible problems due to an unexpected unwinding of the roving can be effectively prevented.
