## Abstract

A tape attaching method for mounting an adhesive tape to an annular frame having an inside opening to thereby support a plate-shaped workpiece through the adhesive tape to the frame in the inside opening thereof. The tape attaching method includes an adhesive tape attaching step of attaching the adhesive tape to the workpiece, the adhesive tape being larger in size than the frame, a frame positioning step of positioning the frame with a spacing defined between the frame and the adhesive tape in the condition where the inside opening of the frame is opposed to the workpiece attached to the adhesive tape, and a tape attaching and cutting step of partially pressing the adhesive tape against the frame by using a roller rotating along the inner circumference of the frame defining the inside opening.

## Claims

### Claim 1

A tape attaching method for mounting an adhesive tape to an annular frame having an inside opening to thereby support a plate-shaped workpiece through said adhesive tape to said frame in said inside opening of said frame, said tape attaching method comprising:
an adhesive tape attaching step of attaching said adhesive tape to said workpiece, said adhesive tape being larger in size than said frame;
a frame positioning step of positioning said frame with a spacing defined between said frame and said adhesive tape in a condition where said inside opening of said frame is opposed to said workpiece attached to said adhesive tape; and
a tape attaching and cutting step of partially pressing said adhesive tape against said frame by using a roller rotating along the inner circumference of said frame defining said inside opening, thereby partially attaching a portion of said adhesive tape to said frame, and also cutting another portion of said adhesive tape in an area of said tape that is not in contact with said frame by using a cutter having a cutting edge where said cutting edge of said cutter is not in contact with said frame, said cutter being arranged adjacent to said roller and on a side of said roller that is closest to an outer side of said frame.

### Claim 2 (depends on 1)

The tape attaching method according to claim 1, wherein said roller includes a hard area and a soft area, said soft area being softer than said hard area.

### Claim 3 (depends on 1)

The tape attaching method according to claim 1, wherein said tape attaching and cutting step further includes nipping said adhesive tape by a pair of nipping members of a holding unit, and raising or lowering said adhesive tape relative to said frame using said holding unit.

### Claim 4 (depends on 1)

The tape attaching method according to claim 1, wherein said tape attaching and cutting step further includes nipping said adhesive tape by a plurality of pairs of nipping members associated with a plurality of holding units, and raising or lowering said adhesive tape relative to said frame using said plurality of holding units.
