Definitions

  • the invention relates to an improved device for zig-zag folding of a flexible strip of textile material fed continuously.
  • the invention relates to the technical sector of machines and equipment for packaging flexible bands made of textile material such as ribbons and similar products.
  • Ribbons and other textile bands produced continuously on looms must be packaged.
  • an old method consists in folding them in a zig zag in a continuous movement back and forth determining lengths of bands.
  • a carriage made up of rotating rollers between which the flexible strip is introduced and which by its alternating movement forms a zig zag and continuously the ribbon is used on an entablature provided for this purpose.
  • the carriage is driven by the aforementioned reciprocating movement and thus makes it possible to obtain, in succession, predetermined strip lengths, as illustrated in FIG. 1.
  • the different lengths of tape must be sent in a package, while maintaining a certain presentation attire.
  • the problem posed is inherent in the nature of the textile band or ribbon which is flexible, foldable by definition. It consists, in holding the different lengths of tape, which tend to sag naturally.
  • the strip is thus introduced between a lower support plane and an upper support plane, while pushing means guide the strips in the strips thus defined.
  • the mechanism described in this patent is complex and does not allow easy adaptability of the system according to the width of the tape, even if there was the possibility of height adjustment of the means exerting the upper support.
  • rollers have only a role in driving and guiding the strip.
  • the object of the invention is to remedy these drawbacks.
  • the solution proposed by the invention is particularly original, simple to implement. It has many advantages in the quality of resistance of the different zig zag folds of the strip, the latter being distributed positively.
  • light items can be folded with the device, according to the invnetion.
  • the device is remarkable in that the improved device for the zig-zag folding of a strip of flexible material fed continuously, of the type comprising an entablature with a rear zone and means for distribution of the fabricated strip, a central zone arranged with a transverse slot allowing the alternating movement of a pair of rollers between which the strip is guided, the said rollers being placed on a carriage driven by means of controls of a transverse movement alternative opposite the aforementioned slot and thus authorizing at the exit of the rollers the crimping of a ribbon, and a front zone authorizing the reception and the evacuation of the parts of the ribbon folded continuously and their evacuation towards the zone packaging, the device further comprising means for pushing the portions of folded ribbons; the device being remarkable in that it comprises two assemblies comprising in particular two pinions, cooperating with a fixed rack arranged transverslament in the entablature, during the transverse movement of the carriage, said pinions cooperating with means associated with the rollers, said means consisting to
  • the device is remarkable in that the means acting on the rollers are freewheels, mounted in opposition.
  • the device according to the invention aims to ensure the zigzag folding of flexible strips, in particular of textile material, according to an automatic continuous setting. These measures is therefore positioned in a known manner on an entablature (1) successively having an area and means (2) for distributing the strip coming from a roll on which the strip has been wound during manufacture, or in bulk according to the prior modalities of this manufacturing.
  • the means (2) represents, without limitation, a guide for returning and presenting the strip to the rollers (4 and 5) for conveying the latter.
  • the central or substantially part of the entablature is arranged with a transverse slot (3) allowing the alternating movement of a pair of rollers (4 and 5), mounted in opposite rotation and between which the end of the strip is guided, then the strip itself, being zig zag folded.
  • the motor means authorizing the transverse movement of a support carriage (7) of the roller pair (4 and 5) are arranged in the lower part of the entablature and protected by protective plates.
  • the folded strip is then conveyed on the front part of the entablature, being guided longitudinally by profiles (6) fixed in any suitable manner.
  • the strip is conveyed towards the front of the entablature and falls into a wrapping or packaging provided for this purpose and not illustrated.
  • the device makes it possible to present the various successive folds of the strip in a vertical position or substantially, on edge and to maintain good hold during the entire advance of the folded strip towards its packaging.
  • the device has two essential features: -
  • a first feature consists in alternately making each of the rollers (4 and 5) positive, thus respecting the direction of travel of the strip, whatever the direction. movement of the carriage.
  • the other particularity consists in acting by means against the strands of the strip part opposite the output of the pair of distributing rollers (4-5) by ensuring pressurization and alternating tension of each of the half parts of strips which have just been executed, thus bringing back, still vertically, the parts of folded strips.
  • the device taken as a whole is first mounted on a carriage (7).
  • the latter comprises, for example, a sole (7-1) possibly U-shaped, and the ends of which are arranged at their upper part to receive support plates (7-2) supporting bearings (8).
  • the assembly can be made in one piece.
  • the bearings are guided along two slides (9 and 10) arranged transversely to the entablature.
  • the carriage can therefore be moved in a reciprocating and transverse movement, relative to the entablature, while being substantially opposite the transverse slot (3) formed on said entablature.
  • the carriage is associated by its lower part with appropriate control means known to those skilled in the art and which can, for example, and without limitation, be constituted by a system of connecting rods or cranks controlled by a motor ensuring the aforementioned back and forth movement.
  • the amplitude of movement of the carriage is adjustable in a known manner and is a function of the length of the plies of ribbons to be obtained.
  • the device is fixed to the carriage, advantageously, in the central and central part of the sole.
  • it comprises a support cap (11) for connecting the two assemblies associated with each of the rollers (4 and 5), said cap being secured by one or more connecting screws. (12) at the sole.
  • rollers are in a plane above the entablature and the other means, in the lower part protected by protective plates.
  • These means include mounted on a shaft (13) (14) corresponding to each roller (4-5), pinions (15) (16) capable of cooperating with a fixed rack (17) disposed on the frame of the entablature between the two slides and in the same plane of them.
  • a spacer and retaining block (18) guides said shafts and is held in position in a fixed plane, by a support structure (24) associated with the base of the carriage, by appropriate means.
  • Two freewheels (19-20) mounted in opposition are positioned on said shafts, above the spacer block, each in close relation with one of the rollers (4-5).
  • rollers (4-5) are each arranged above each free wheel, being indexed by appropriate means. These two rollers are in contact with one another, while a spacer plate (21) is mounted at the end of the rollers in a horizontal plane and ensures their protection and maintenance.
  • said plate receives rods (22-23) connecting and guiding said rollers (4 and 5), the end of said rods being associated with the aforementioned means to complete the mounting of the device.
  • This block is adjustable in height relative to the plane of the entablature, the height corresponding to the width of the ribbon. this avoids the movement or an unexpected movement of the ribbon, before it passes between the rollers (4-5).
  • the device according to the invention has means ensuring good resistance of the portions of ribbons bent in a zig zag and preventing its compaction or sagging.
  • the device thus comprises a means acting during the shaping of the folds of ribbons and alternately, depending on the position of the carriage and therefore of the rollers (4 and 5), on the portions of folded ribbons.
  • This action consists, in the exercise of a pressure and a temporary push, against the part of the ribbon folded and accompanying the direction of movement of the carriage.
  • This means consists of a belt (27), arranged at the outlet of the rollers (4 and 5), automatically accompanying the movement of the carriage, this, in order to keep the layers or parts of ribbons folded and to facilitate the release of the setting device. in fold, by a progressive advance movement of the ribbon conditioned in zig zag.
  • this belt is fixed at these ends (27-1) (27-2) on rods or axes (28), mounted in a fixed position on the entablature but, in a substantially advanced position, relative to the front plane rollers (4-5) thus giving an angulation ( ⁇ ).
  • two return axes (29-30) of the belt At the rear end of the entablature are arranged two return axes (29-30) of the belt, in a fixed position. Said belt is also guided, on either side, of each roller (4-5). Indeed, and in an original way, the spacer plate (21) fixed above each roller is arranged, to receive from its front ends, and in an eccentric plane with respect to the axis of the rollers, two return rods (31-32) fixed in a removable manner, by bolting or the like.
  • two protective plates (33-34) are provided on the front face of the above-mentioned device.
  • the means used are extremely simple, easy to implement.
  • the distance of the carriage's alternative movement will depend on the width of the folds of the ribbon.
  • the active length of the belt strands will naturally vary depending on the range of movement of the carriage.
  • the advantages of the device according to the invention are in particular the following: -
  • the textile band is positively distributed - Strips of different widths can be folded without changing the setting - Light items, such as lace, can be folded with this device -
  • the length of the belt can be adapted according to the needs and lengths of setting of the textile bands.
