Definitions

  • the present invention relates to a cutting device for Cut off jump threads, the two consecutive Quilting seams of two quilt sections of a contiguous Connecting ceiling track, at two ends of the jump thread.
  • the invention further relates to a device for manufacturing of quilts.
  • the industrial production of quilts is generally done by superimposing endless webs of at least an outer material, a filler and an under material to one Linerboard.
  • these endless webs by attaching several, usually parallel to each other Stitched seams along the ceiling panel.
  • This thread which during the interruption of the sewing process being pulled loosely over the ceiling track is generally considered Called a jump thread. So it's a piece of thread, each from the end of a stitching of a blanket to the beginning of the stitching a next ceiling is enough.
  • the object of the invention is to automate this process, to permanently correct severing the jump threads enable.
  • the object is achieved by a thread trimmer solved that between a ceiling track and a jump thread is retractable and the cutting elements for cutting the Has a jump thread at the ends.
  • the length of the jump thread is known, e.g. 20 cm.
  • the approximately Retracted laterally or transversely to the longitudinal axis of the ceiling panel Thread cutter clamps the jump thread and the cutting elements separate the jump thread to the desired, here 20 cm from each other distant places.
  • the cutting device an alignment device for aligning the cutting elements immediately adjacent to the ends of the jump thread.
  • the thread trimmer introduced between the ceiling track and the jump thread and the cutting elements are aligned that this immediately adjacent to the bolt during the cutting process lie. This will ensure that the jump thread always immediately adjacent to its ends separated will, resulting in increased aesthetic quality of the finished Quilts leads.
  • the cutting device a tensioning device for tensioning the jump thread.
  • a taut thread is easier to cut than a thread limp thread.
  • a tensioning of the jump thread facilitates before severing the jump thread this severing.
  • tensioning the hanger makes its ends easier accessible because of such a jig the Jump thread standing opposite the stitching at an angle can be aligned.
  • the cutting device a fixing device for fixing the jump thread on.
  • a tense one Thread is, as previously mentioned, easier to cut than a flabby.
  • the cutting device no longer needs to be precise in the middle of the jump thread are introduced as the cutting the two ends of the jump thread no longer take place simultaneously got to. This will increase the reliability of the cutting process clearly increased.
  • the thread trimmer is the Cutter can be inserted transversely to the stitching.
  • the alignment device has two movable arms on which the Cutting elements are attached.
  • these are movable arms equipped with a spring device, the this spreads.
  • Such arms can, e.g. in the leading part of the thread trimmer, be pivoted, and spread to the rear.
  • the cutting process takes place when the ends of the jump thread on the cutting elements attached to the arms are to be passed.
  • the distance between the cutting elements be varied during the cutting process.
  • tolerances in the length range of a certain Length of a jump line but it is too possible, differently long jump threads, such as these, e.g. at different lengths of quilts can occur, cut off, without additional settings necessary.
  • the alignment is solely by the two movable arms which are attached to a base body, takes place and no further adjustment devices are necessary,
  • the system is also characterized by a special mechanical Simplicity.
  • the movable arms at the rear ends each have an eyelet on.
  • the thread trimmer has a basic body which is approximately is sword-shaped.
  • Such a main body has a tapering forward Front section, an elongated longitudinal beam and followed by a crossbeam.
  • the elongated longitudinal beam allows the greatest possible Spreading area for the attached arms.
  • the crossbar pushes the ceiling track on a wide surface together and thus makes the ends of the jump thread better accessible.
  • the crossbar may still be at its leading edge in addition, have a concave profile, making it as a guide can serve for the movable arms.
  • the clamping device is through Covers formed resiliently mounted the cutting elements cover.
  • the fixing device acts also as a clamping device.
  • the jump thread is passed through the fixing device after retracting the thread trimmer between Deckenbahn and Sprungfaden added and thereby, that the thread trimmer is moved, cocked.
  • the fixing device is as Clamp formed.
  • the clamp has a forwardly directed inlet opening, in which the thread enters automatically. In a trailing Section of the clamp, the thread is then attached to the thread trimmer fixed.
  • the fixing device holds a truncated jump thread.
  • the jump thread can after cutting up on easy way to be removed from the ceiling track. remains a cut piece of thread after cutting the Jumping on the ceiling, it may happen that this Thread piece in a further manufacturing step with a Quilt is sewn, which is aesthetically undesirable is.
  • the fixing device Means for ejecting a picked-up thread.
  • a front edge of the thread trimmer Beveled on her side facing the jump thread.
  • the front edge of the Thread cutter protrudes only slightly above the ceiling panel, so that he can easily between the ceiling track and the Jump can be introduced.
  • the slope at the Feather facing side of the thread trimmer ensures that while moving the thread trimmer the Jump thread is safely passed over the thread trimmer.
  • the invention further relates to a device for manufacturing of quilts, which after a sewing section a thread trimming section comprising a cutting device according to the invention having.
  • the manufacturing process can thus be completely automated become.
