Abstract
PURPOSE:To improve working efficiency by automating loadings and unloadings of wafers to a grinder. CONSTITUTION:When a web 12 is held into a holding hole 13 of a carrier 11 at the loading position P, it is carried to a lapped position R by intermittent movements of the carrier in the endless structure 11, namely onto the upper side of a lower lap plate 16. Then, an upper lap plate 15 comes down, it tucks the wafer 12 between with the lower lap plate 16, whereby the wafer 12 is applied the determined surface pressure. After that, while lapping compound is being supplied upon the lapping portion, lapping is done by turning the upper and lower lap plates 15, 16 in the same direction for a determined lapse of time. When the lapping is over, the upper lap plate 15 is sent up, again the carrier 11 makes its intermittent movements and carries the wafer 12 to the unloading position Q. At said position Q, the wafer 12 is moved onto a chute part 24, and after it is stopped by a stopper 25, it is held into a cartridge 26 by a pusher 27.
