СПОСОБ ИЗГОТОВЛЕНИЯ МЕХОВОЙ НИТИ

Способ изготовления меховой нити заключается в накручивании полоски меха на нить-основу из немехового материала, концы которых с одной стороны скреплены между собой. Нить-основу предварительно скручивают, поворачивая ее не скрепленный с полоской меха конец. Затем нить-основу за оба конца вращают вокруг ее продольной оси в противоположном предварительному скручиванию направлении, при этом осуществляют подачу полоски меха с наклонным расположением относительно нити-основы. Предложенный способ обеспечивает увеличение прочности, эластичности и улучшение внешнего вида меховой нити. 3 ил.

Fur comber - for long-haired furs with vacuum withdrawal

The material is carried on a permeable conveyor for presentation to the combing cylinder, and as the conveyor turns down and back on its end roller, a vacuum zone grips the material and withdraws it from the combing cylinder. At the end of the vacuum zone the material is released, and pulled by gravity to a further conveyor for return to the operator. The purpose is to prevent the operator withdrawing the fur from the combing cylinder by hand, and to prevent the materials being carried round by the combing cylinder.

Scraping treatment for leather hides - eliminates unpleasant manual labour and improves utilisation of scraping machine

The scraping treatment involves bringing a hide from a supply station, inserting about half the length of the hide between the open tools of a scraping machine, closing the tools and drawing out the hide which scrapes the first half. The hide is then reversed and the untreated half inserted into the scraping machine for treatment. The half-treated hide is now returned to a waiting station upstream of the scrapping machine and pref. alongside the supply station. The scraping machine is then fed alternately with a fresh hide from the supply station and a reversed, half-treated hide from the waiting station. Hides sent forward from both the supply and waiting stations to the scraping machine are pref. suspended by hook attachment of trolley of an overhead runway conveyor. The runway is pref. a closed circuit track so that a trolley can move around from the rear of the scraping machine back to the supply station.

Heating appliance for sheet-like hand tools, especially wetting-off irons for leatherware production

The invention relates to a heating appliance for sheet-like hand tools, especially wetting-off irons for leatherware production, with an electrically heated bearing plate. The disadvantage of the known heating appliances for this purpose is that they have a very high electrical power requirement, since they radiate heat to all sides in an unimpeded manner. The result of this is, also, that burns occur on the hand because of these highly heated and easily accessible bearing plates. A third disadvantage is that the poor heat transmission from the heated bearing plate to the wetting-off iron necessitates increased heating times. These disadvantages are eliminated, according to the invention, in that a further clamping plate of approximately the same shape and dimensions, having high thermal conductivity and moving back resiliently, is arranged above the bearing plate, and the two plates are accommodated in a container lined with heat-insulating material, for example glass wool, having a lateral ...

Inspection table, especially for leather, includes a projector for projecting a light pattern and a camera connected to a computer to recognize faults

A projector (17) projects a light pattern (19), e.g. grid lines, on to an animal skin (12). The pattern is scanned by a camera (21) placed at some distance (22) from the projector (17) and the image analyzed by a computer (24) that recognizes faults by the distortion of the reflected pattern. The faults are classified by volume and can be marked at a work station (23). An Independent claim is also included for the process of identifying faults by these means. The classification can be based on the depth or volume of the fault. Preferred Features: The projector and camera can be traversed on a gantry (16) to cover the whole area. The skin (12) can be carried on a conveyor and held by suction. The outer contour of the skin can also be determined.
