Definitions

• the invention relates to a method for marking hides, skins and similar sheet-like materials.
• the material When processing hides, skins and the like the material is usually subjected to a chemicai processing e.g. in connection with tanning, dyeing etc as well as a mechanical processing in the form of splitting, ie. lamination, folding, embossing, punching, cutting etc.
• chemicai processing e.g. in connection with tanning, dyeing etc as well as a mechanical processing in the form of splitting, ie. lamination, folding, embossing, punching, cutting etc.
• the processing proper takes place in a complex flow where raw skin lots are being worked up. This is not always in parallelly running production lines because according to requirements some objects are being col ⁇ lected in intermediate stocks and others are being partially processed. At the same time a grading as to quality, dimensions etc takes place into a number of different lots.
• the coding may be performed by a simple punching of small through-going holes and by means of optoelec- tronic measuring instruments and light through these holes the punch code can be read in a reliable and simple manner.
• the code may be read with a simple measuring instrument.
• Fig. 1 is a top view of a skin after the coding
• Fig. 2 is an enlarged cross-section of the skiri" seen in the direction II-II in Fig. 1
• Fig. 3 is the skin placed in a reading apparatus.
• OMPI 4 ⁇ make WIPO made in a skin at one of its corners. These holes may of course be placed at any other place of the skin where they cause the least inconvenience.
• the code itself is built up as a binary punch code wherein a hole means logical 1 and no hole logical 0.
• a hole means logical 1 and no hole logical 0.
• each individual skin may be marked with ia. a serial number and a date number.
• Fig. 2 shows a cross-section of a hole 2 and the dot- ted lines moreover indicate that the skin 1 by being split can be split in a number of parts 3 that will all contain the given punch code.
• Fig. 3 shows an embodiment of a reading apparatus
• O PI comprising a light table 4 with a light cabinet 5.
• the skin 3 is placed on this light cabinet so that light can penetrate the punch code 2, 8, 9.
• the carriage can be carried manually over the punch code.
• the carriage 6 has- a decoder for measuring the dis ⁇ tance between the individual holes in the code.
• the • measured distance between the reference holes 8, 9 is compared by means of a calculation program with the original distance between these holes 8, 9 « Any pos ⁇ sible deviation is used for correcting the longitu ⁇ dinal deformation that may have occurred during the processing of the skin.
• the described method can also be performed by means of other than a punch code.
• radioactive or mag ⁇ netic trace elements that can either be embedded by pressing in a rod or be injected by means of a solu ⁇ tion, it is possible in a similar manner to mark skins and read the code by means of a generally known suit ⁇ able apparatus.
