Pattern discs are marked with the indication for machine type (see 4.1.1), gauge (see 4.1.2), stitch row number (see 4.1.3), notation (see 4.1.4), starting of the notation (see 4.1.5), fitting borehole (see 4.1.6),direction of rotation (see 4.1.7), and classification of guide bars (see 4.1.8).
A pattern disc is intended for a certain gauge, which shall be indicated in accordance with ISO 8188 (see Figure 1).
NOTE 1 If a pattern disc is intended especially for a machine partly set with needles, a slash is indicated behind the gauge and the divider of the needle insert.
EXAMPLE 1 E6/3 means gauge E6 with the divider 3 for the needle insert 1 full/2 empty//in the needle bar and thus, existing gauge E2.
NOTE 2 For indirectly controlled pattern gear, an equivalent gauge results from the gauge and the lever ratio of the shog lever for the pattern disc, which is additionally indicated in brackets.
EXAMPLE 2 E8 (E12) means a gauge E8 and an equivalent gauge E12, which results from the lever ratio 1,5 of the shog lever.
The stitch row number can be indicated for pattern discs with the index C, for RR flat warp knitting machines with the index DC. Besides as alternative, the stitch row number can be indicated as transmission ratio in form X:1, whereas, X is the number of machine revolutions per pattern disc revolution.
NOTE 1 For RL flat warp knitting machines, the number of machine revolutions per pattern disc revolution corresponds to the number of stitch rows.
NOTE 2 16C respectively 16:1 means that the RL stitch row number is 16, i.e. for 16 machine revolutions the pattern disc turns once.
NOTE 3 12DC respectively 12:1 means that the RR stitch row number is 12, i.e. for 12 machine revolutions the pattern disc turns once.
The notation steered by the pattern disc is indicated in form of the lapping notation. At the same time,the numbering starting from zero is to be applied with the increment 1 (see Eigure 1).
NOTE In 4.1.2 Note 1, the lapping notation corresponds with the needle insert in the needle bar, i.e. for the machine partly set with needles the notation will be indicated according to this needle setting and not in regard to the maximum possible needle setting.BS ISO 11676 pdf free download.
