Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for cutting a double knotted nape loop.

Cut double-bonded naps are produced on circular knitting machines of the Lip type with circular and dial plate beds, or on Singelbe-type circular knitting machines with auxiliary sinker bars.

In circular rip knitting machines, the cutting of the napped loops occurs when the napped loops are formed by a cam on the shank of the stopper which exits in the direction from the center of the circular rip knitting machine, and are pulled into one course of the double knotted napped. It is carried out by waking up. That movement of the stroke causes the forming napped loops to be cut by a sharp blade located on the upper side of the shank. However, the napped loops are distorted upon cutting and their length is therefore not uniform. The circular knitting machine is therefore equipped with pressure rollers that press against the circumferential surface of the dial plate head, thus stabilizing the napped loops.

The drawbacks of that device are that it is relatively expensive and unreliable.

Singelbe, cut double knotted pile with circular knitting machine!
! In this case, the machine is equipped with an auxiliary sinker bar on which a nap sinker is mounted in a displaceable manner, the nap sinker being movable vertically with respect to the working movement of the knitting needles. The nap sinker is equipped with a nap catch designed to pull the nap loop to a predetermined length. Like the napped loop, the knitting needles are controlled by a cam system. The formed napped loop is therefore deformed and pulled to the side of the circumferential edge of the auxiliary sinker bar groove, apart from the needle row. For molding, the top of each napped loop is cut by pulling the napped loop top into the groove by the napped sinker from these two arms about the circumferential edge of the auxiliary sinker bar groove.

The nap catch of each sinker is provided for that purpose with a rectangular recess 7 having sharp side edges on its upper surface and into which the nap loop is engaged.

The drawback of this device is the large amount of waste produced by the top of the napped loop. This debris increases fouling and the desired constant removal, such as by g & pull, which is also undesirable from a power consumption point of view.

Each groove of the auxiliary sinker bar is formed by a pair of sinkers arranged therein, one napped sinker is movable and its napped catch is provided with a recess, the edge of which is placed near the center of the circular knitting machine. Cutters are also known which are provided with a side blade, to which another cutting sinker is fixed, and which is provided with another side blade at its leading edge.

When the blade of the cutting sinker is passed by the blade of the napped sinker on which the napped loop is placed, the napped loop is cut without waste. However, the drawback of that device lies in the unreliability of cutting the whole pilaf loose due to the dulling of the blade, and in particular the creation of a gap between the two sinkers, so that the pilaf loops are not cut but just stuck. It will only be written.

To cut the napped loop, the force is also applied from an inverted U-shaped cutting sinker removably mounted inside the groove of the auxiliary sinker bar and a napped sinker removably mounted inside the cutting sinker. It was designed to become something. This napped sinker has a rectangular recess 7 on its upper surface with a sharp side edge into which the napped loop is engaged. The cutting sinker is defined on its drawing board with a sharply beveled double front part. The two sinkers are controlled by a cam system.

At the same time the top of the napping loop is placed into the cutting sinker by the napping sinker, the latter moves in the opposite direction and the top of the napping loose is cut by the napping sinker through the cooperative action of its bevelled double front part and the sharp side blade of the napping sinker. Cut by. The flaws in this are even more.
z, rx redundancy I R-) Attachment pattern 0
→ This is due to the formation of a relatively large amount of debris with a micrometer drop.

The above-mentioned disadvantages and disadvantages are controlled by a cam system,
and is reduced by the cutting device for double-bonded nap loops of the present invention, which is characterized in that it is formed by the cooperative action of a pair of nap sinkers with sharp side edges by one recessed hole from each upper part. Ru.

It is advantageous if a pair of nap sinkers is installed in the guide groove of the auxiliary sinker bar or if a pair of nap sinkers is installed in one radial groove of the dial plate head. .

It is also possible for one of the cooperating nap sinkers to be installed inside the guide groove of the auxiliary sinker bed and the other in the radial groove of the dial plate head.

According to the invention, one of the pair of erect sinkers is provided with a pick-up projection disposed laterally at the mouth hole, which projection is in sliding contact at its end with an adjacent erect sinker of the second pair. There are also advantages.

The advantage of the force according to the invention lies in the significantly increased reliability of cutting the entire piloerection loop without any distortion of the loop. A further advantage is that a leveling of the surface of the naps formed results in a reduction in consumption of about 20 to 25% of the total amount of material. Compared to other conventional devices, the device of the present invention reduces soiling as well as purchase price.
