(Cl. 216—20) 2 1 more particularly to a manual means for apply— below the outlet II. The cover I9 is hinged to the front of the cup and has the sides 20, 2| ex ing paper tape to the joints of wall board panels. Among the objects of the invention is to facili tate ?lling and covering the seams formed by the abutting edges of wall board panels. Another object is the application of an adhesive tending upwardly past the lip 22 at the top of the opening I ‘I, and forming a chute through which the tape 23 passes. The tape is threaded upwardly through a slot 24 in the bottom of the cup then upwardly This invention relates to taping machines and through the space between the cover I9 and the plaster to the tape as it ?ows through the ma lip 22 and around the roller 5. The tank II is chine. A further object is to cause the tape to auto 10 beveled at 25, 26 to accumulate the plaster 21 therein so that the plaster remaining will ?ow matically feed through the machine as it is forced against the wall by the machine being guided along the seam. . , Other objects and advantages will appear as the description proceeds. In the speci?cation and drawing the invention is disclosed in its preferred form. But it is to be understood that it is not limited to this form, because it may be embodied in modi?cations with through the outlet I1, against the tape 23 pass ing upwardly through the chute. The whole area of the tape is provided with small perforations _ permitting the escape of air from between the inner surface of the tape and the contacting plaster 21. The tape within the chute is forced back against the cover I9 by the plaster which is leveled off by the lip 22 as the tape emerges in the spirit of the invention as de?ned in the 20 from the chute. The thickness of the plaster coating may be adjusted by the screw 28, threaded claims following the description. through the rod I and bearing against the cover In the one sheet of drawings: I9.
