An apparatus is described for machining on the face side a negative mold for a profile element (1) which is made of thermoplastic foamed material, forms the branch of a channel of a shaft floor and can be applied in an interlocking manner to a profile strand for the main channel, comprising a table (3) for receiving the profile element (1) to be machined and with a support (5) which is movable along a predetermined planar path for a curved heating wire (4) extending in one plane along the profile. In order to provide simple machining conditions it is proposed that the support (5) can be moved along a path corresponding to the axial progress of the profile strand for the main channel, that the heating wire (4) has a progress which corresponds to the contour of the profile strand for the main channel and that the support (5) which is held in a rotatable manner about an axis perpendicular to the plane of the path can be rotated within the terms of a permanent perpendicular orientation of the heating wire plane relative to the path of the support (5).
