On the other hand, when the corresponding resistance imparting piece 25A is placed in the non-operating position by the perforation signal of the signal card 30, the corresponding jack 12 moves straight ahead on the front side without becoming stuck. The magnetic cam plate 6 of the sorting magnet 62 can move freely back and forth without contacting the application piece 25A.
4 and are sorted and moved backwards while being sucked in.

Then, bat 1 of jack 12 was sorted behind it.
2A is led out almost as is to the preparation position YD, and the butt of the knitting needle 3 corresponding thereto is also led out to the knitting preparation position Y as is, but the jack 1 sorted forward
As the second butt 12A is advanced by the jack knitting needle advance cam 66 on the pond side, it pushes out the butt 3B of the corresponding knitting needle 3 to a position slightly in front of the inner end of the knitting needle advance cam 56 on the pond side.
Thereafter, the forward movement of the jack 12 is blocked, but the butt of the corresponding rope needle 3 continues to move against the knitting needle advancement cam 56.
The jack 12 is guided forward to the needle selection position Z by
is retracted to the preparation position YA by the jack retraction cam 67 on the other side. When the carriage 39 is turned back and slid, the signal card 30 is initially transferred so that a new signal string corresponds to the long leg 32A of the signal reading piece 32, and then, as described above, the signal card 30 is sorted back and forth. Butt 3B of knitting needle 3
is introduced from the knitting preparation position Y and the cross-needle position Z and used for a predetermined pattern knitting (two-color simultaneous knitting, tack knitting, etc.), and then at the rear side in the carriage sliding direction, the same as above By the method described above, the front and rear sorting action of the butt 128 of the jack 12 and the sorting action of the butt 3B of the knitting needle 3 in accordance with the sorting action are performed.

Incidentally, when the butts 3B of the knitting needles 3 are sorted back and forth and after the sorting, the open end of the leaf spring 10 is elastically inserted into the lower recess of the butt 3B of the knitting needles 3 at the knitting preparation position Y that is sorted backwards. Therefore, the butts 3B of the knitting needles 3 that are sorted behind the knitting needles do not move inadvertently.

In particular, there is no possibility that the knitting needles 3 that are sorted forward will suddenly move forward through the stitches as the butt 3B moves forward. In addition, the working knitting needle section (knitting preparation position Y
The butt 12B of the jack 12 corresponding to a certain knitting needle 3 in the knitting needle section (disposed in the knitting needle section) is set to the rest position XA, and the butt 12B of the jack 12 corresponding to the other knitting needle 3 is set to the ready position Y.
By arranging the knitting needles at the respective jacks 12 at the preparation position YA, only the knitting needle group corresponding to the jack 12 at the preparation position YA is placed at that jack 12.
It is possible to perform a partial pattern stripe called a so-called one-point pattern by selecting according to the selection method.

That is, for example, if the total number of working line needles 3 is 34, the butts 12B of the jack 12 corresponding to the middle 24 knitting needles 3 are placed in the ready position YA, and the five knitting needles on each of the left and right sides are arranged. Bat 12 of jack 12 corresponding to 3
B are respectively placed in the rest position XA, and the carriage 39
By sliding the needles, the 24 middle knitting needles 3 are sorted forward and backward through the corresponding jacks 12, but the five green needles 3 on each side of the left and right sides are not sorted, and therefore, after the sorting, Partial pattern knitting is performed where pattern knitting is performed in the part corresponding to the 24 knitting needles 3 in the middle, and simple plain knitting etc. is performed in the part corresponding to each of the 5 knitting needles 3 on both the left and right sides and no pattern is formed. will be done. As described in detail above, the present invention is directed to a needle selection device comprising a carriage slidably mounted on a needle bed equipped with a jack, a jack alignment path, a sorting means, and a jack knitting needle advancing cam. In particular, a lowering member and a sorting magnet are provided between the jack alignment path and the jack needle selection advance cam, and a resistance imparting member is provided on the needle bed, and the resistance imparting member imparts low resistance. Jacks that are not attracted to the sorting magnet and to which the resistance is not applied are attracted to the sorting magnet, and each jack is sorted back and forth, and the sorted jacks are placed on the front side by the jack knitting needle. It is designed to act on the forward cam.

Therefore, when selecting the jack, the jack is not locked by a special locking means, but resistance is applied by mere contact, so that the needle selection device can be extremely simplified.

In addition, since the jacks are sorted by being attracted to or not attracted to the sorting magnet depending on whether or not contact resistance is imparted to the jacks, the jacks can be sorted at high speed, and in an extremely light and easy-to-use manner. It has excellent effects such as being able to sort. Brief explanation of drawings 1st
