Dependent Claim
72 words
Blast nozzle assembly for pneumatically loosening thread ends of rotating textile coils comprising a blast nozzle, means for transporting a textile coil past said blast nozzle in a given travel direction, means for pivotally mounting said nozzle, and means for controlling pivoting movement of said nozzle in accordance with the travel of the textile coil within a limited angular range in and opposite to the given travel direction of the textile coil.
Claim 3
Dependent Claim
83 words
Blast nozzle assembly for pneumatically loosening thread ends of rotating textile coils comprising a blast nozzle, means for transporting a textile coil past said blast nozzle in a given travel direction, means mounting said nozzle for pivoting the same within a limited angular range in and opposite to the given travel direction of the textile coil and means for forcibly controlling the pivoting of said nozzle-mounting means in accordance with the travel of part of said textile coil-transporting means past said blast nozzle.
Claim 4
Dependent Claim
83 words
Blast nozzle assembly for pneumatically loosening thread ends of rotating textile coils comprising a blast nozzle, means for transporting a textile coil past said blast nozzle in a given travel direction, means mounting said nozzle for pivoting the same within a limited angular range in and opposite to the given travel direction of the textile coil and means for forcibly controlling the pivoting of said nozzle-mounting means in accordance with the travel of part of said textile coil-transporting means past said blast nozzle.
Claim 5
Dependent Claim
44 words
Blast nozzle assembly according to claim 2 including entrainer means extending from said blast nozzle and engageable by the textile coil as the latter is transported by said part of said transporting means over a given distance corresponding substantially to said limited angular range.
Claim 6
Dependent Claim
40 words
Blast nozzle assembly according to claim 2 including entrainer means extending from said blast nozzle and engageable by said transporting means as a part thereof transports the textile coil over a given distance corresponding substantially to said limited angular range.
Claim 7
Dependent Claim
70 words
Blast nozzle assembly according to claim 2 wherein said transporting means carries the textile coil in substantially vertical position as it is transported in said given travel direction and including a substantially rod-shaped entrainer member extending from said blast nozzle and engageable by the substantially vertical coil as the coil is transported by said part of said transporting means over a given distance corresponding substantially to said limited angular range.
