The warp knitting machine for jacquard-patterned pile-knit fabrics includes pile yarn carriers which are individually movable, according to a selected pattern, in the place of each needle to form a shed of the selected pattern forming and the non-selected pile yarns whereby the tip of the shed is at the knock-over point of the needle. A guide reed is movably arranged between the pile yarn carriers and a pile sinker and includes a laying edge which crosses the pattern-forming pile yarn of the shed. The guide reed performs lateral and sinking movement to overlay the selected pile yarn.

A tool-changing mechanism for machine tools of the kind in which tools can be inserted into a spindle. A tool magazine receives several tools and a double-ended tool-changing arm is provided on each of its two ends with gripping mechanisms. The tool-changing arm is rotatable about an axis of rotation which is parallel to the spindle axis and the tool-changing arm can be moved along the direction of its axis of rotation. The tool-changing arm can also be pivoted, between a working position and a rest position, about a pivot axis which is parallel to its axis of rotation.
