Definitions
- the invention relates to a nozzle for welding plastic flooring and wallcovering.
- the object of the invention is to provide a nozzle which will help to eliminate the problems outlined above.
- Said nozzle is characterized in that it comprises a metal sleeve with a tubular rear part, intended to be connected to a conduit of some kind for the supply of hot air to the inside of the sleeve, and with a dome-shaped and completely closed front end or tip, there being two diametrically opposed, obliquely forward directed orifices for the expulsion of hot air, the sleeve lacking further openings between said orifices.
- This nozzle thus is instrumental both in heating the filler material and in smoothing the surface. It may also be applied to the sealing of small holes in the plastic flooring.
- the nozzle is preferably rotationally symmetrical, and the dome-shaped tip is preferably essentially a half-sphere.
- the word tip hence does not indicate that the front end is pointed.
- the word tip has the same meaning as for example in finger-tip.
- the two orifices are preferably located immediately behind the tip. According to a preferred embodiment, the material of the central part of the tip is considerably thinner than that of the sleeve in the area of the orifices.
- Fig. 1 is a view in perspective of the nozzle according to the invention, as seen from ahead at an angle;
- Fig. 2 is an elevation of the same nozzle
- Fig. 3 is a sectional view along the line III—III of Fig. 2.
- the nozzle illustrated by the drawings comprises a tubular brass sleeve 1 with a blunt, half-spherical smooth tip 2.
- the sleeve 1 is rotationally symmetrical.
- a hot-air conduit 3 may be connected to the rear end of the sleeve 1.
- a handling collar 4 To facilitate the assembly and disassembly of the sleeve 1 and the conduit 3 there is provided a handling collar 4.
- the material of the central part 8 of the tip 2 is thinner than that of the tubular part 5.
- a suitable thickness is 1 - 2 mm. If the material is thicker, the temperature of the air must be increased to keep the tip 2 hot enough. This may on the other hand cause the hot air to damage the plastic material in the vicinity. Remaining plastic on the tip may also be scorched as one changes working area.
- the nozzle may of course be modified within the scope of the invention.
- the nozzle need not be entirely straight. It is thus fully conceivable that the tubular part be bent, so as to facilitate work in hard-to-reach corners and nooks.
