TH36715B - Methods and tools for continuous feeding of textiles for making double folds. - Google Patents

Abstract

DC60 (14/09/47) Herein reveals a method and tool for double folding with continuous feeding. The textile is folded according to the boundary guide tool along the folding guide line by reducing the angle. Fold in small increments. The movement of the folded angle decreases gradually. A number of guide rollers pass through the Press it against the straight edge across the fabric's cross-section. Immediately before the procedure on the fabric which was folded a complete two There is one detector tool provided to adjust to detect the actual position of each The upstream side edge and pivot rollers of these detector instruments adjust to Changing the textile cross-section angle in relation to the machine's direction of operation. The interpolation between the detector apparatus and the guide roller causes the guide roller to The fabric is centrifuged and, by means of which the lateral edge is moved in pre-determined positions, reveals the method and apparatus for folding into two by continuous feeding. The guiding tool limits the fold along the fold guide line by gradual reduction of the fold angle, in that the movement of the fold angle is reduced gradually. A number of guide rollers pass through the Press it against the straight edge across the fabric's cross-section. Immediately before the procedure on the fabric which was folded a complete two There is one detector tool provided to adjust to detect the actual position of each The upstream side edge and pivot rollers of these detector instruments adjust to Changing the textile cross-section angle in relation to the machine's direction of operation. The interpolation between the detector apparatus and the guide roller causes the guide roller to It is centrifuged and, by virtue of which it moves the lateral edge, to the predetermined positions.

Claims (4)

Disclaimers (all) that will not appear on the advertisement page: 1.Method for continuous folding of textiles with a feeding in the running direction of the machine. Machine continuously in two along the fold guide extends in a parallel direction to the working direction of The machine in the cross-sectional direction perpendicular to the operating direction of the said machine. Continuous feeding of such material in the operating direction of such machines according to the machine. The guiding hand limits the fold guide line, so the fabric may be folded by a number of guide rollers. Are arranged periodically in the operating direction of such machines Such a guiding roller that is rotating Can be in the operating direction of the machine, touching the opposite, transverse edge of the textile. And with multiple rotating shafts across that lateral edge of the said textile at an opening of 90 ° or less in the direction in which case the textile is fed. Therefore, the fold angle of such a textile in the cutting direction. It may be reduced little by little. The downstream side of the guide rollers and immediately before the folding step of such textiles are complete, an adjustable detector tool that detects various positions of the side sections. Various in such cross-sectional directions Was rolled upstream of various detectors as To the side so that it is clamped to touch each of the aforementioned side And by relying on to change The cross-sectional angle of such textiles is related to the machine operation direction and the interpolation valve. Between the detector apparatus and the crankcase roller and the energizing of the said throttle On the basis of the difference between the received data From the tool, the detector shows the actual location of the edge and the location information that Expect the side edges. Therefore, such centrifugal rollers may Relying on the lateral edge movement in the expected position 2. The aforementioned method according to claim 1, in the case of textiles, consists of at least One of the non-woven textiles Woven textiles and plastic films can be stretched. Flexibly or inflexibly 3. The aforementioned approach pursuant to claim 1 or 2, in the event of such a textile target that is limited Front waist area The back of the waist. And the crotch area of a disposable wear-pull 4.Tool for continuous textile folding with double-direction continuous feeding. The way of working the machine along the folding guide line extends in parallel with the machine operating direction. The machine in the cross-sectional direction perpendicular to the operating direction of the said machine. The instrument consists of a number of instruments, first at the upstream side. In the operating direction of such machines and adjust To feed the non-coiled textile in such a transverse direction. The second tools are at the downstream side in the direction of operation of the said machines and Adjusted to convey such textiles that are being rolled, folded in two. The interpolation between the first and the second. And adjusted so that it is pressed against the said fabric along the curling guide line, so that the fold of the said textile in two; Several guide rollers are arranged at intervals. In the direction of machine operation And adjusted so that the handle stretches in contact with the side edges Each such guide roller has a shaft. Rotate the cross section of the side edge of the fabric at an opening angle of 90 ํ or less in the transverse direction. Of such textiles; The guide rollers are located at the downstream side of the guide rollers and adjusted to allow grip. Contact with the aforementioned side edges of the textile and in addition To spin so the angle Of the cross-section of the guide roller in relation to the said lateral edge of the textile Said may have been changed; The detector tool is downstream of the centrifugal roller and is adjusted to detect. The position of the side edge in the said cross-sectional direction The adjuster causes the centrifuge roller to centrifuge on the basis of a break The difference between the data sent by the detector tool shows the true position of the margins. Side above, and the data shows the expected position of the side edge to move the segment. The side edges go as expected.
