Abstract
An apparatus for the heat treatment of textile material comprises a plurality of nozzle boxes extending across the operating width at least on one side of the length of material. The nozzle boxes are fed from a front face and have openings discharging in a direction towards the length of material and a fan is disposed at the feed end of these nozzle boxes. The fan is a radial flow fan. It is arranged with its axis of rotation at right angles to the plane of the length of material on the long side of the apparatus.
Claims21
An apparatus for the heat treatment of a textile material arranged to extend in a plane, especially a tenter frame device for the heat treatment of a passing length of textile material, which comprises several nozzle boxes arranged transversely across the operating width of said textile material at spaced intervals from one another, said nozzle boxes being fed with heated air through openings at front end faces and having openings discharging the heated air in a direction toward the length of textile material, a fan being disposed at the feed openings of said nozzle boxes, said fan being a radial-flow fan and being arranged, with its axis of rotation, at right angles to the plane of the length of textile material on a longitudinal side of the apparatus whereby said heated air is introduced directly into said nozzle boxes from said longitudinal side parallel to the plane of said length of textile material, the air flowing from the nozzle boxes onto the textile material being then discharged between said spaced nozzle boxes in the same flow direction to the other longitudinal side of the apparatus and being returned, after deflection and heating, to the fan by way of a duct formed therebetween, and a heating unit being provided at the other longitudinal side that is readily accessible from the outside of said apparatus, said fan deflecting the heated air returning via said duct by 180.degree..
An apparatus for the heat treatment of a textile material arranged to extend in a plane, especially a tenter frame device for the heat treatment of a passing length of textile material, which comprises nozzle boxes extending across the operating width on both sides of the length of textile material, said nozzle boxes being fed with heated air through openings at front end faces and having openings discharging the heated air in a direction toward the length of textile material, two radial-flow fans being arranged one above the other on both sides of said textile material and attached to a shaft driven by a motor, each fan having an air intake means, and air discharge means, each fan being disposed with the air discharge means adjacent to the feed openings of said nozzle boxes and being arranged with its axis of rotation at right angles to the plane of the length of textile material on one longitudinal side of the apparatus whereby said heated air is introduced directly into said nozzle boxes from said longitudinal side parallel to the plane of said length of textile material and means on the other longitudinal side of the apparatus causing heated air deflected from the textile material to flow over the textile material and to return to a fan on said one longitudinal side, said means on the other longitudinal side of the apparatus including a discharge opening through which the air is passed before being returned to a fan on said one longitudinal side, said opening being positioned on the same side of the operating width of the length of textile material as the fan to which the heated air is returned and heater means located in said discharge opening for providing additional heat to said heated air prior to the heated air being returned to said one longitudinal side of the apparatus.
An apparatus for the heat treatment of a textile material arranged to extend in a plane, especially a tenter frame device for the heat treatment of a passing length of textile material, which comprises nozzle boxes extending across the operating width on both sides of the length of textile material, said nozzle boxes being fed with heated air through openings at front end faces and having openings discharging the heated air in a direction toward the length of textile material, two radial-flow fans being arranged one above the other on both sides of said textile material and attached to a shaft driven by a motor, each fan having an air intake means, and air discharge means, each fan being disposed with the air discharge means adjacent to the feed openings of said nozzle boxes and being arranged with its axis of rotation at right angles to the plane of the length of textile material on one longitudinal side of the apparatus whereby said heated air is introduced directly into said nozzle boxes from said longitudinal side parallel to the plane of said length of textile material and means on the other longitudinal side of the apparatus causing heated air deflected from the textile material to flow over the textile material and to return to a fan on said one longitudinal side and heating units being provided above and below the length of textile material, said units being controllable independently of each other.
An apparatus for the heat treatment of a textile material arranged to extend in a plane, especially a tenter frame device for the heat treatment of a passing length of textile material, which comprises nozzle boxes extending across the operating width on both sides of the length of textile material, said nozzle boxes being fed with heated air through openings at front end faces and having openings discharging the heated air in a direction toward the length of textile material, two radial-flow fans being arranged one above the other on both sides of said textile material and attached to a shaft driven by a motor, each fan having an air intake means, and air discharge means, each fan being disposed with the air discharge means adjacent to the feed openings of said nozzle boxes and being arranged with its axis of rotation at right angles to the plane of the length of textile material on one longitudinal side of the apparatus whereby said heated air is introduced directly into said nozzle boxes from said longitudinal side parallel to the plane of said length of textile material and means on the other longitudinal side of the apparatus causing heated air deflected from the textile material to flow over the textile material and to return to a fan on said one longitudinal side, and a heating unit at the top side of the material being designed to have a larger heating capacity than a heating unit associated with the underside of the material.
