Definitions

  • the invention relates to apparatus for steam treating the uppers of shoes and is particularly concerned with an improved apparatus for steam treating or mulling the outside of such uppers while keeping the interior in dry condition.
  • the shoe uppers are either introduced by using feeding arrangements having continuous advancing means or they are manually introduced into the apparatus which is provided with the means necessary for producing the water vapor and is closed on all sides so that concentrated action of the water vapor on the uppers of the shoes is obtained.
  • the moistening of the shoe upper should preferably be effected only on the outside, i.e. on the grain side of the leather, while the inside of the upper should remain as dry as possible.
  • the requisites for controlling the steam treatment against the grain side of the leather are continuously becoming more rigid, because the dyed leathers that are treated by modern methods, for example by priming, are very sensitive.
  • a moisture permeable conveying device is provided on which the uppers are placed.
  • a water trough with heating coils is provided below the conveyor for generating a steam or vapor atmosphere, and above the conveyor, spray nozzles for hot water.
  • the problem is solved by providing apparatus whereby the inside of the shoe upper is subjected to the action of an air current and means are provided for the additional vaporizing and distribution of the spray water.
  • the apparatus is provided with means for producing an air current that is directed into the inside of the shoe uppers. Furthermore, above the shoe uppers to be treated a heating element is provided which additionally heats and distributes the quantities of water that are sprayed laterally and upwardly.
  • FIG. 1 is a section taken transversely of the apparatus in accordance with the invention
  • FIG. 2 is a fragmentary view illustrating a modified embodiment of the invention.
  • the apparatus is equipped with a housing 1 in the form of a tunnel or the like through which a conveyor 2 carrying the uppers of the shoes to be treated travels continuously.
  • This conveyor may be in any desired form.
  • Tubes 7 having spraying nozzles 8 are passed upwardly through the water baths 4 and 5.
  • the water supplied through the tubes 7 to the spraying nozzles 8 is heated while passing through the water baths 4 and 5 without it being necessary to introduce any additional heat.
  • Additional heating elements 10 are provided above the conveyor track for the shoe uppers 3 which are located at the apex 9 of the tunnel 1.
  • the heating body '10 prevents the formation of condensation water in the area of the apex of tunnel 1, which could result in forming droplets and, therefore, water drop spots upon the very sensitive drained outside of the shoe uppers 3. It is understood that for the treatment of the shoe uppers 3 water that has been treated with a wetting agent to reduce surface tension in a known manner is used, so that it can better penetrate the leather of the shoe uppers 3 which contain fatty substances.
  • these means are constituted by ventilators in the form of fans 11. It is, of course, possible to employ any other means for introducing the air, for example, air nozzles or jets 12 which are supplied from a common source as shown in FIG. 2, or similar appliances.
  • the upwardly directed air stream produced prevents the entrance of the steam atmosphere into the inside of the shoe uppers 3 and accordingly prevents moistening of the inside. Simultaneously, the remaining air current which may leave the uppers from the top adds to the further more extensive whirling of the steam vapor in tunnel 1.
  • the interior of the uppers treated remains dry.
  • the glue utilized for this purpose can be fully effective. The gluing effect is not impeded by moisture absorbed on the inside of the upper by the upper leather.
  • the conveyor 2 may, as mentioned above, be in any form desired, but a conveyor in the form of a fabric is preferred. It is, of course, also possible to provide the apparatus in tunnel shape without imparting any particular conveying means. Finally, it is also possible to construct the apparatus in the form of a cabinet.
  • the drawing shows a cross section.
  • the individual parts of the apparatus are repeated, depending on the length of the tunnel.
  • the spray nozzles 8 are in two series rows; also the means for producing an air current, such as fans 11, may be arranged in series one behind the other.
  • the heating elements extend longitudinally in the full length of tunnel 1.
  • the apparatus is constructed in tunnel form with a conveyor for continuously supplying the device with the shoe uppers to be treated.
  • the measures in accordance with the invention may also be applied in processing cabinets where a certain number of shoe uppers are introduced at the same time for simultaneous treatment and are removed after the steaming has been eifected.
  • Apparatus for steaming the outside of the uppers of shoes while maintaining the inside in dry condition comprising a housing having a lower end and an upper portion forming an apex, means in said housing for supporting said uppers, means for directing an air current upwardly into the interior of said uppers, heating means disposed at the apex of said housing, means disposed laterally and proximate the lower end of said housing for projecting a water spray into said housing and against said heating means for additionally vaporizing said spray and with the aid of the air current directing vapor downwardly onto the outside of said uppers.
