A face of a sheet, e.g. of glass, is moved past an extrusion nozzle to deposit a plastic filament adjacent a first edge thereof. The movement is interrupted when a corner is reached. The nozzle and sheet are moved away from each other to detach the filament adjacent the corner and the sheet is rotated to present its next edge to the nozzle while retaining the continuity of the filament. The nozzle and sheet are then returned to depositing position and the relative movement resumed to deposit the filament adjacent the next edge. The apparatus includes means for raising the sheet from conveyor belts and raising the extrusion devive by a greater amount, and then turning the sheet by a suction cup arm, the sheet being supported by rollers during the turning. A detector monitors the position of the sheet and controls the operation of the apparatus.
