An autonomous strip laying device for marking the ground includes a rolling frame supporting a reel of strip to be unwound, a strip unwinding assembly, elements for applying the strip on the ground including an applicator roll, a device for sectioning the strip and an assembly driving the frame and actuating the different devices and the unwinding elements. The assembly unwinding the strip and the elements for applying the strip are, at least during the unwinding and laying of the strip, mutually synchronized in rotation by synchronizing elements.

There is provided herein a new apparatus for applying tape such as masking tape to surfaces for purposes of protecting those surfaces from exposure to subsequent treatment of adjacent surfaces by paint, varnish, stain, and the like. The device of the instant invention includes a rotably mounted spool of tape which is fed past a cutter blade, over a guide pin and around an application roller. The cutter blade is positioned to be clear of the tape during normal operation. However, when the tape is tensioned by braking the rotation of the tape spool by application of a hand brake, the tape path is drawn down into contact with the blade, thereby severing it. Additionally, the instant invention utilizes a plurality of guide wheels to space the tape that is deposited by the instant invention apart from the surface that is adjacent to the taped one.

A device for placing individual road markers in desired configurations along a road surface comprises an application wheel having at least one aperture connected to a frame by an axle. The frame and application wheel are then connected to a trailer that is pulled along behind a pulling device. The apertures of the application wheel are dimensioned to receive a part of the road marker in a position tangential to the surface of the application wheel. As the application wheel rolls over the surface, the base portion of the marker contacts the road surface. An adhesive portion of the marker causes the base of the marker to become adhered to the road surface. As the application wheel continues to roll, the standing reflective portion of the marker is withdrawn from its position within aperture of the application wheel, and remains in a desired location upon the road surface.

A roadway marking system, comprising a roadway marking tape and a plurality of spaced reflective roadway markers having a white reflective front surface, a red reflective rear surface and a elevated crest, is applied to an upper surface of a roadway. The roadway marking tape has a lower surface with an expandable adhesive material and a plurality of contoured roadway spikes, projecting from the reflective roadway markers which are exposed from the lower surface through the adhesive material. When downward pressure is applied to the upper surface of the roadway marking tape and the elevated crest of the reflective roadway markers, the roadway marking system becomes permanently attached to the upper surface of the roadway with the adhesive material providing a permanent adhesive seal between the marking tape and the roadway surface. Once attached to the roadway, the roadway marking system provides an audible, tactile and visual warning to a driver traveling on the roadway over the roadway marking system.
