Eschenbach discloses a method of forming twisted slub yarn comprising a core yarn 10 and an
effect yarn 12. To accomplish this, the path of the effect yarn 12 being fed into an air jet 14 is
lengthened by a path deviator assembly 50, thereby reducing the linear velocity of the feed of the effect
yarn into the air jet 14. When a solenoid valve 74 is intermittently deactivated, the effect yarn is
released from the expanded position and the excess yarn is sucked into the air jet 14, wherein the
filaments of the effect yarn 12 are allowed to curl into loopy yarn and intermingle with the filaments of
the core yarn 10.
It is the examiner’s position that Altman discloses securing loopy yarn to a sheet to form a
female connector member, but that Altman does not disclose adhesively securing the loopy yarn onto
the sheet. It is also the examiner’s position (answer, pg. 5) that it would have been obvious to use
adhesive to secure the loopy yarn 16 of Altman onto the sheet 11 since, a) Altman discloses (col. 2,
lines 11-12) that the loopy yarn may be “secured to material 11 in any suitable manner,” b) securing
loopy material to a sheet is “old” in the art, and c) adhesive securing is simpler and more effective than
stitching. The examiner further explains (answer, pg. 5) that since there is suggestion in Altman to
provide more than one loopy yarn on the sheet:
