Machine for preparing road surfaces and forming traffic regulating lines thereon
First Claim
1. A machine for forming an essentially linear traffic regulating sign on a road surface and along a given path, by applying and securing a prefabricated tape material above a predominantly thermoplastic primer layer on said surface, comprising a composite motor vehicle adapted to be driven on said road surface along said path, said vehicle carrying, in the direction of its travel for service, washing means for washing a substantially narrow strip of said surface having its center-line about at said path, drying means for drying said surface area strip, primer layer and prefabricated tape material applying and pressing means for applying a tape material above a primer layer on the said washed and dried road pavement surface area, and a structure having parts above said surface area and forming a ceiling wall and side wall forming curtain means hung from side parts of said structure to provide a confined environment above said surface area so that the latter is located and the washing, drying and applying means operate in a space sheltered from external weather and splashes.

Abstract
A method for forming a traffic regulating line or like sign on a roadway pavement even if the surface pavement is very wet and generally during very unfavorable weather, the method comprising maintaining the surface area on which the sign is to be formed and the means for forming it into a confined environment sheltered from the weather, and includes the sequential steps of washing said area, drying it and locally heating the pavement up to a temperature near to that at which a primer layer composition essentially melts where contacted to said surface, and then applying on said surface an at least predominantly thermoplastic primer layer and a sign forming tape material bonded thereabove. There is also described a machine designed to be driven along said road pavement and including means designed for performing the said sequential steps in said sheltered environment.
