Process and apparatus for making bulked filament yarns

Claim 1

AN APPARATUS FOR PRODUCING BULKED FILAMENT YARNS COMPRISING MEANS (1) FOR CONTINOUSLY ADVACING TWO GROUPS OF CONTINUOUS SYNTHETIC FILAMENTS LENGTHWISE TOWARDS A MERGING ZONE WITH THE FILAMENTS IN ONE GROUP HAVING THE CAPABILITY OF BEING CRIMPED TO A SUBSTANTIALLY GREATER EXTENT THAN ARE THE FILAMENTS OF ANOTHER GROUP AND (2) FOR CAUSING SAID GROUPS OF FILAMENTS TO FORM A BUNDLE AT SAID MERGING ZONE, MEANS FOR CAUSING THE FILAMENTS IN THE TWO GROUPS WHEN COMBINED INTO SAID BUNDLE TO BE INTERLEAVED AND INTERMIXED SUFFICIENTLY TO CAUSE THE FILAMENTS FROM EACH GROUP TO BE DISTRIBUTED SUBSTANTIALLY THROUGHOUT THE CROSS-SECTION TO THE BUNDLE AND COMPRISING MEANS FOR SUBJECTING THE FILAMENTS FROM BOTH GROUPS TO SUFFICIENT GAS CURRENTS TO OPEN UP THE FILAMENT FROM SAID GROUPS, SAID ADVANCING MEANS BEING OPERABLE TO ADVANCE THE FILAMENTS FROM SAID GROUPS WITH THE FILAMENTS FROM EACH GROUP SUFFICIENTLY FREE FROM EACH OTHER WHILE BEING SUBJECTED TO SAID GAS CURRENTS TO CAUSE FILAMENTS FROM THE TWO GROUPS TO OPEN UN AMD THE FILAMENTS FROM THE TWO GROUPS TO BECOME INTERLEAVED AND INTERMIXED SUFFICIENTLY WHEN SAID OPENED FILAMENTS ARE IN SAID BUNDLE TO CAUSE THE FILAMENTS FROM EACH GROUP TO BE DISTRUBUTED SUBSTANTIALLY THROUGHOUT THE CROSS-SECTION OF THE BUNDLE, AND MEANS FOR FORMING SAID BUNDLE INTO A SINGLES YARN HAVING THE FILAMENTS STILL CONTINUOUS AND THE FILAMENTS FROM SAID ONE GROUP CRIMPED TO AN EXTENT SUBSTANTIALLY GREATER THAN ARE THE FILAMENTS FROM THE OTHER GROUP AND HAVING THE FILAMENTS FROM EACH GROUP DISTRIBUTED THROUGHOUT SUBSTANTIALLY THE CROSS-SECTION OF THE YARN.
