    • This invention relates to primary processing of animal hides and more particularly to methods for cleansing cattle hides and to apparatus for carrying out same. According to the proposed method, washing, soaking and removal of dung from the surface of the hides are carried out simultaneously and continuously under copious irrigation of the moving hides with water and the hides are then clamped in position essentially along the axis of movement, while the removal of dung is effected by carding their hair covering and subsequent removal of surface moisture. An apparatus for carrying out said method comprises a tank for washing hides, a pair of belt conveyers arranged parallel to each other, and a pair of chain conveyers for grasping a hide and clamping it along its axis with its hair covering downwards during travel, and shafts with carding teeth are situated on either side of said chain conveyers, set at an angle sufficient for the maximum coverage of the surface of the hide being processed, said teeth being also set at an acute angle to the tangent to the surface of the shaft in a direction opposite to its rotation. The apparatus comprises also a pair of rolls with ribs arranged along the generatrix on the surface of said rolls and coming in contact with the hide for the wringing of surface moisture therefrom. This design provides for higher productivity and better quality of the hides being processed.
    • 本发明涉及动物皮革的初级加工,更具体地涉及用于清洁牛皮的方法和用于进行其的装置。 根据所提出的方法,在水分移动的皮革的大量灌溉下,同时且连续地从皮革表面洗涤,浸泡和除去粪便,然后基本上沿着运动轴线夹住皮革,同时 通过梳理他们的头发覆盖物和随后去除表面水分来实现粪便的去除。 用于执行所述方法的装置包括用于洗涤皮革的罐,一对彼此平行布置的带式输送机,以及一对链条输送机,用于抓住皮革并沿其轴线夹紧,其头发在行进期间向下覆盖,以及 具有梳理齿的轴位于所述链式输送机的任一侧上,设置成足以使待处理的皮革的表面的最大覆盖度的角度,所述齿还设置成与轴的表面的切线成锐角 在与其旋转相反的方向上。 该装置还包括一对辊,其具有沿所述辊的表面上的母线布置并与皮革接触以用于从其中拧紧表面水分。 该设计提供了更高的生产率和更好的质量的被处理的皮革。

    • An apparatus for tanning skins in a rapid and efficient manner includes a closed tanning tank and a plurality of storage tanks for storing the various liquids employed in tanning skins. The skins to be tanned are hung in the tanning tank. An air tight door is provided in the tanning tank for loading and unloading the skins. The tanning tank also has an inlet/outlet pipe for filling and emptying the tanning tank, which pipe is connected through a valve to an elevation pump. A respiration pipe having means for producing a gas which is chemically inert to tanning liquids is also provided on a tanning tank. Each of the storage tanks has an outlet pipe with a valve for controlling the flow of liquid therethrough which is connected to the elevation pump. Some of the storage tanks are airtight and have outgoing pipes connected to an outgoing pipe on the tanning tank to permit gases to flow between each of those storage tanks and the tanning tank. Other devices which may be operably coupled to the apparatus include an internal stirring system, an internal heating system and a dissolution tank. Also, a plurality of tanning tanks may be provided.
    • 用于以快速和有效的方式鞣制皮肤的装置包括封闭的鞣制罐和用于储存在晒黑皮肤中使用的各种液体的多个储存罐。 要鞣制的皮肤挂在晒黑罐中。 在鞣制罐中设有一个气密门,用于装卸皮肤。 鞣制罐还具有用于填充和排空鞣制罐的入口/出口管道,该管道通过阀门连接到升降泵。 具有用于生产对鞣制液体具有化学惰性的气体的装置的呼吸管也设置在鞣制罐上。 每个储罐都具有一个出口管,该出口管具有一个阀,用于控制连接到升降泵的液体的流动。 一些储罐是气密的,并且出口管连接到鞣制罐上的输出管,以允许气体在这些储罐和鞣制罐之间流动。 可以可操作地连接到装置的其它装置包括内部搅拌系统,内部加热系统和溶解槽。 此外,可以设置多个鞣制罐。
