AN APPARATUS FOR FACE-SIDE MACHINING OF A PROFILE ELEMENT FORMING A NEGATIVE MOLD FOR THE BRANCH OF A CHANNEL IN A SHAFT FLOOR

摘要

An apparatus is described for machining a face side of a profile element forming a negative mold for a branch channel interlockingly connectable to a profile strand of a main channel comprising a table (3) for receiving the profile element (1) and with support (5) which is movable along a predetermined planar path for a curved heating wire (4). The support (5) is movable along the axial progress of the profile strand. The heating wire (4) has a progress corresponding to the contour of the profile strand for the main channel. The support (5) is rotatable within the terms of a permanent perpendicular orientation of the heating wire plane relative to the path.
