Abstract: A power strapping tool having an anvil and a tensioning wheel adapted to engage with overlapping portions of a strapping looped about a package and extending to a supply. The tensioning wheel is rotatable in a direction as to tension the loop of strapping and maintain such strapping tensioned while overlying portions thereof are connected to each other and then in an opposite direction to relax and flex away from the underlying strapping portion a span of the overlying strapping extending between such wheel and the location of strapping connection to thereby position such flexed, overlying strapping portion for easy severence. In the preferred embodiment, rotation of the tensioning wheel is also relied upon to effect projection of a knife between the overlying flexed and the underlying strapping portions and to then again tension the overlying strapping portion whereby the flexed strapping is urged against the projected knife to thereby sever the applied loop of strapped from its supply.

Abstract: A protective vinyl transfer sheet material and a method for laminating such transfer sheet material to a vinyl substrate. The transfer sheet material consists of a film of plasticized vinyl resin releasably supported with measurable adhesion on one side of a continuous, flexible, non-fibrous cellulosic carrier, particularly regenerated cellulose sheet. In the method of the present invention, the vinyl film is bonded under pressure with heat to the vinyl substrate, after which the cellulosic carrier may be readily stripped from the laminate, leaving the firmly bonded vinyl film as a protective overcoating for the substrate.

Abstract: Process of making a polyester resin using a zinc esterification catalyst and a hindered phenol stabilizer.

Abstract: A strapping machine for applying a tensioned strap loop horizontally about the girth of an object in which a yoke for lacing a strap about an object and means for tensioning and securing such strap are together adjustable as a unit, first into a desired projected position vertically of the object which is to be strapped, and then into a horizontal projected position in which the strap tensioning and securing means are directly adjacent to such object immediately prior to performing their respective functions.
