Definitions

• the invention concerns improvement of the structure for arrangement of mutual position of at least two consequent loops in a row of knitted fabric.
• the mutual position of loops in a row of weft knitted fabric is set in fact by the length of sinker loops.
• the mutual position of loops in the row is regular and the length of individual loops is equal, the appearance of the weft knitted fabric corresponds with aesthetic requirements.
• the aesthetic appearance of the weft knitted fabric may be harmed in case of breach of regularity, for example in the surroundings of terminal loops of rows or in case of creation of space objects, like for example the pouch of reverse-knitted heel of a sock or the wedge of panty-stockings as known from the file WOO2006CZ00028.
• the first known method of securing the terminal loops is based on the principle that the free end of the thread following the terminal loop is fixed in the consequent loops of the previous row in the form of so called tuck loops. That means that the free end of the thread is partially tied in the knitted fabric. This is sufficient to avoid development of holes, but it is usually not possible to avoid enlargement of the terminal loop by this method. That is why this method is used only in cases when the terminal loop enlargement is acceptable and when there prevails the mechanical simplicity of the machinery.
• the other known method is based on the fact that the loop is knitted in double. That means that the terminal loop is simultaneously knitted by two threads - the thread that will be excluded from knitting and simultaneously by the thread that was used for knitting the previous row.
• This method can reliably secure the terminal loop from ripping and enlargement, but it has even two disadvantages.
• the first disadvantage means that the mechanical equipment is more complicated than in previous case.
• the second disadvantage will appear mainly in case of creation of space objects, as described above.
• the cause of the disadvantage is based on the fact that needle loops of neighbour loops are not interconnected, so in case of strains of knitted fabric in locations where individual rows continue each other on sloping respectively perpendicular basis, the loops usually get deformed and so there appear non-aesthetic holes.
• the task of the invention is to improve the structure for arrangement of mutual position of at least two consequent loops in a row of knitted fabric, mainly in locations, where - due to technological reasons - the regular structure of the weft knitted fabric is breached, e.g. in case of switching on or off the operation system or in locations where individual rows continue each other on sloping respectively perpendicular basis.
• the suggested invention taking into consideration the current state of the art - shows it novel character mainly on the basis of the fact that the same thread is used for setting mutual position and distance of sinker loops of at least two consequent loops as well as for setting mutual position of their needle loops. Due to the new characteristics, the mutual position of at least two consequent loops in the row of knitted fabric is in fact independent on consequent rows and so there does not occur the generally know enlargement of loops and consequent development of non-aesthetic holes in knitted fabric.
• Figure 1 shows known version of structure for securing the terminal loop using the tuck loops
• Figure 2 shows known version of structure for securing the terminal loop by duplication
• Figure 3 shows known space structure when the rows of the knitted fabric are mutually perpendicular
• Figure 4 shows securing of the terminal loop of the line according to suggested invention
• Figure 5 shows securing of the pair of loops according to the invention in space structure, when the rows of the knitted fabric are mutually perpendicular.
• Figures 1 up to 3 are designed for explanation of novelty and differences compared to the existing state of the art.
• Figure 1 shows a sample of an incomplete row 1, terminated by the terminal loop 2.
• the sinker loop 2 ⁇ is followed by the free end of the thread Z2_, where there are created the tuck loops Z3_ and 2A Knitting of the tuck loops Z3_ and IA.
• t0 the following row 3 means reaching of partial stabilisation of the terminal loop 2.
• Figure 2 shows securing of terminal loop by duplication.
• the incomplete row 4 is terminated by the terminal loop A ⁇ .
• the terminal loop 4J. is doubled / duplicated as it is simultaneously knitted from two threads - from the thread used for knitting of the incomplete row 4 and from the thread used for knitting the previous line 5.
• FIG 3 shows the space structure where the mutually following rows are in fact perpendicular.
• the structure is known for example from the file WOO2006CZ00028.
• the vertex of the wedge 6 consists of loops 8 and 9, that are mutually secured by the tuck loops 8J 1 and 9.1.
• the vertex of the wedge 7 is terminated by a pair of loops 10 and 11, mutually secured by tuck loops 10.1 and 11.1.
• Figure 4 shows sample securing of a pair of loops - the last loop 14 and the previous loop 13 of the incomplete row 12.
• thread 17 that continues the sinker loop 14.2 is initially put counter the direction of knitting on the needle loop 14.1 of the last loop 14 and consequently to the needle loop 13.1 of the previous loop 13-
• thread 17 in the direction of knitting is put on the needle loop 15.1 of the loop 15, to which is knitted the previous loop 13 and consequently to the needle loop 16.1 of the loop 16, to which is knitted the last loop 14.
• the described laying of the thread 17 to needle loops 13.1, 14.1, 15.1, and 16.1 may be even repeated - multiple.
• the above stated securing is not limited only to the pair of consequent loops, this procedure may be used for securing of three or possibly more consequent loops. In such a case it is necessary to put the thread on needle loops of several previous loops.
• Figure 5 shows securing of two consequent loops in case of space object where individual rows of the knitted fabric are in fact perpendicular to each other.
• the object consists of two opposite wedges 18 and 19 of in fact triangular shape, with their vertices terminated by a pair of loops - the terminal loops 14 and previous loops 13_. Securing of the pairs of loops is performed analogically, in such a way that the thread 17 ⁇ continuing the sinker loop 14.2, is put initially against the direction of knitting to the needle loop 14.1 of the last loop 14 and then on the needle loop 13.1 of the previous loop 13.
• thread 17 in the direction of knitting is put on the needle loop 15.1 of the loop 15, to which is knitted the previous loop 13 and consequently on the needle loop 16.1 of the loop 16, to which is knitted the last loop 14.
• putting the thread 17 on needle loops 13.1, 14.1, 15.1, and 16.1 may be repeated, multiple, while the securing is not limited only to the pair of consequent loops; this procedure may be used for securing of three respectively more consequent loops. In such a case it is necessary to put the thread on needle loops of several previous loops.
• the main advantage of the proposed invention is based on the fact that the pair of consequent loops 13, 14, has its needle loops 13.1, 14 ⁇ tightened by the same thread 17, used for creation of the above stated loops.
• the connection is in fact non-flexible and it does not allow change of distance between the two needle loops. Due to the above stated, there can not occur the well-known enlargement of the loops and development of non-aesthetic holes in the knitted fabric. More, the structure for securing the pair of consequent loops can be performed by already known mechanical device.
• the invention is designed for improvement of appearance and uniformity of weft knitted fabric in locations where it is necessary - due to technological reasons -to switch off and then on any knitting process from the knitting process and in cases where - while creating space objects like for example heel pouch or wedge of seamless panties - the individual rows of knitted fabric follow each other in sloping or perpendicular way.
