In the filling out with jointing material of the slot between window frames or door frames and an opening in the wall of a building, it is well-known for a "back-stop" for a final jointing to be introduced into this slot, namely by the insertion of a jointing string in the slot. With the invention, this insertion can easily be effected while achieving a constant and expedient depth, in that for the pressing-in of the string use is made of an implement with a handgrip to which is connected a part for support contact against the front of the frame, and a pressing-in part which can hereby be extending into the slot and can thus press the string in to precisely the desired depth. The two parts are preferably integrated in a profiled roller with a cylindrical contact part and a protruding disk part for penetration into the slot. |
