Description

Dec. 22, 1953 L. TE STRAKE FLAT WRAP-KNITTING MACHINE Filed Feb. 2, 1950 1 miniu Patented Dec. 22, 1953 UNITED STATES PATENT OFFICE 2,663,173 FLAT WARP-KNITTTNG Lambertus te Strake, Deurne, Netherlands Application February 2,1950, Serial No. 141,891
Claims priority, application'Netherlands December 8, 1949 3 Claims.
The invention relates to a flat warp-knitting machine with two series of alternately reciprocable needles and at least two series of thread guides, which are so movable with respect to each other that thread crosses are formed above the series of needles.
The invention aims at improving this machine so that it is possible to obtain a straight fabric in which the loops be at one side of the fabric.
Such a fabric is more suitable for e. g. upper garments and underwear than the fabric obtained by the above mentioned machine.
According to the invention this is obtained in that the needles of both series of needles are situated substantially in the same plane and the needles of the first series are situated between the needles of the second series.
Owing to the fact that the fabric is pulled at one side of the needles and the latches of the needles are also situated at one side, a onesided fabric is obtained.
A practical embodiment of the invention is obtained in that the needles of the first and of the second series are mounted in separate needle bars, which are so driven that they are reciprocable with respect to each other in the same plane of motion.
The needles of one series of needles engage the thread cross formed by the displacement of the thread guides.
Consequently, since the needles lie in the same plane of motion each time they can engage the thread cross immediately and the needles need not wait until the thread cross is formed at the correct place. Therefore the machine now can operate more rapidly since the series of needles need not undergo a period of rest in order to allow the thread crosses to pass.
Besides by this the advantage is obtained that both needle bars are mutually balanced-out by their opposite movement.
According to the invention the construction of the machine is materially simplified, owing to the fact that the needles of both series are slidably supported in one single needle bed.
The invention will be elucidated by an embodiment.
Fig. 1 is a cross-section near the needle bed of the fiat knitting machine;
Fig. 2 is a perspective view of a part of the needle bed.
In Fig. 1 the thread guiding means are indicated by the numerals I and 2 and they extend along the whole working width of the machine. Each thread guiding means is in the shape of a rod having a guides. 1 The threads 3 and 4 come from the yarn beams, and pass through the grooves or thread guides of the thread guiding means to the fabric. The thread guiding means I and 2 are moved relative to each other lengthwise of the needle bed 9 whereby thread crosses are formed above the latter.
The fabric is pulled from the needles by means of the rolls 5 and 6.
The needles consist of short upper needles I and long lower needles 8, both slidably supported in a needle bed 9.
The bed is connected on the counter piece Ill.
The needles I are reciprocated by means of a common needle bar II and the needles 8 by means of a common needle bar [2. The needles are provided with a tongue l3 with which they fit in a notch of the needle bar. By means of a closure plate [4, l5, resp. the needles are fixed. The needle bars II and I2 are driven by means of connecting rods l6, l1 resp. which may be driven by a common shaft.
I claim:
1. A flat warp knitting machine comprising in combination: a needle bed, a first series of needles reciprocably arranged at one side of said needle bed, a second series of needles reciprocably arranged at the same side of said needle bed for movements in the same plane as the first series of needles, the needles of the second series being arranged between the needles of the first series, a first needle bar associated with said first series of needles for reciprocating same, a second needle bar associated with said second series of needles for reciprocating same, first and second actuating means connected with said first and second needle bars for alternate reciprocation thereof and of the two series of needles associated therewith, and at least two thread guiding means arranged above said needles, each thread guiding means including a series of thread guides, and said two thread guiding means being movable relative to each other lengthwise of the needle bed so as to form thread crosses above the latter.
2. A flat warp knitting machine comprising in combination: a needle bed, a first series of latch needles reciprocably arranged at one side of said needle bed, a second series of latch needles reciprocably arranged at the same side of said needle bed for movements in the same plane as the first series of latch needles, the needles of the second series being arranged between the plurality of grooves or thread 3 needles of the first series, a first needle bar associated with said first series of latch needles for reciprocating same, a second needle bar associated with said second series of latch needles for reciprocating same, first and second actuating means connected with said first and second needle bars for alternate reciprocation thereof and of the two series of latch needles associated therewith, and at least two thread guiding means arranged above said latch needles, each thread 10 guiding means including a series of thread guides, and said two thread guiding means being movable relative to each other lengthwise of the needle bed so as to form thread crosses above the latter.
3. In a fiat warp knitting machine as claimed in claim 2, each of said thread guiding means in cluding a bar provided with a series of grooves for guiding engagement with threads.
