SURFACE TREATING DEVICE FOR PLATE−LIKE WORK
Document Type and Number:
WIPO Patent Application WO/2004/048040
Kind Code:
A1
Abstract:
A surface treating device for plate−like works capable of uniformly surface−treating both front and rear surfaces of the works in a short time, comprising tumblers (1) allowing a plurality of plate−like works (2) to be inputted thereinto and rotatable around the center axis (a) and a plurality of abrasive grain projection means (105) projecting abrasive grain to the plate−like works into the tumblers, the abrasive grain projection means being such formed that the projection directions thereof can be altered independently of each other, wherein the plurality of plate−like works (2) are inputted into the tumblers (1), abrasive grain is projected from a plurality of directions (A) and (B) while the tumblers are rotated, the works are surface−treated by the projection from mainly (A), abrasive grain is provided, by the projection from (B), into a work space (V) involving the plate−like works (2) in the tumblers near the tip thereof in rotating direction to promote the reverse rotation of the plate−like works so as to shorten a time for surface treatment.
