ABSTRACT:
Tip seal material 22 is provided on a tip seal reel 12 mounted on a reel support spindle 14. Tip seal material 22 is unwound from the reel 12 by a driven roller 26 of a tip seal material drive and metering mechanism 16. A tool tip assembly 18 with a passage 62 guides tip seal material into a scroll tip seal groove 52 of a scroll 24 inserted in a rotatable scroll assembly fixture nest 78. As the driven roller 26 feeds tip seal material 22 into the tip seal groove 52, the tip seal material rotates the scroll and moves the tool tip assembly 18 along shaft 54, which mounts in support members 56. A knife assembly 64 severs the tip seal material 22 when the proper length of tip seal material has been advanced by the driven roller 26. The driven roller 26 resumes feeding the tip seal material 22 after the severing operation. The resumed feeding results in the remaining severed piece of tip seal material being pushed and transferred from the passage 62 and into the scroll tip seal groove 52.
