Abstract: A tax stamp perforator and notcher applies a diagonal line of spaced apart perforations on a tax stamp for subsequent application to a cigarette pack. The stamp is glued or otherwise applied to the cigarette pack normally across the back of the pack and one of the sides thereof. When the cigarette pack is opened the tax stamp is torn along the line of perforations. In order to facilitate rapid application of tax stamps to a production line of cigarette packs, notches in the form of lines of increased densification are applied to each stamp in the area where the stamp is bent around the side of the cigarette pack. These lines of increased densification are arranged parallel to the edge of the cigarette pack, and preferably one of the lines lies along the edge of the cigarette pack to thereby reduce the ability of the tax stamp to spring back away from the pack when glued to the pack. This feature enables the stamps to be applied to the packs at high production rates.

Abstract: A method of making a fire hose including the steps of extruding a tube having inner 12 and outer coverings of elastomeric material on a woven jacket made from woven synthetic textile yarns and having a weft which is unusually highly crimped. The extruded tube is placed in a confining mould or sheath having an internal diameter substantially the same as the external diameter of the hose, curing the material of the tube by internal application of heat and pressure, pressing the outer covering into tight engagement with the sheath. The sheath effectively prevents radial expansion of the hose during the curing and the outer covering is thus embossed with the surface topography of the inner surface of the sheath upon removal of the sheath. The hose thus formed has good diametral swell properties and consequently reduces the frictional forces in relation to the amount of water flowing through the hose.

Abstract: The present invention provides novel apparatus for punching or drilling of a plurality of elongate, slanting bores or holes in a substantially solid slab made of a relatively rigid, penetrable material such as plastic. The apparatus comprises a punching or drilling chamber having a substantially planar top wall. A series of spikes angle downwardly and at an angle from the top wall. A feed end allows slabs of material to be fed into the punching chamber onto a planar support bed, where the slab is secured from further movement relative to the support bed. The support bed is movable in reciprocating motion upward and downward in the punching chamber in a direction parallel with the longitudinal axes of the spikes which extend downwardly from the top wall of the chamber. During the upward motion, the slab of material is forced into the spikes which pierce the slab and forms the elongated bores or holes therein. In the downward cycle, the spikes are withdrawn from the slab of material.
