  • Page 14 Pressing unit: The pressing unit has to be connected to an additional central steam unit with interconnected solenoid valve or to a steam generator. Attention: To avoid condensation water it is recommended to use a short teflon hose (approx. 2.5 m max.) with small diameter. And the hose should not sag to avoid that condensation water is collected.

    3.4.2 Machine positions (Fig. 4) C A U T I O N ! . Danger of injury! Entanglement hazard for clothing or hair and danger of finger injuries and needle punctures! When checking the positions while the machine is turned on, keep your fingers and hands away from moving parts.

  • Page 17: The Feed (Fig. 5 And Fig. 6)

    The feed (Fig. 5 and Fig. 6) The transport or the speed of the pressing unit is controlled automatically by the deflector roll ( Fig. 5) (1). (see also “4.8.1 Adjusting the stitch length“) After the needle plate, the loop of the belt has to be routed through underneath the deflector roll before it is fed into the opening of the pressing unit.

  • Page 19: Instructions For Use

    Instructions for use Needles and threads The sewing quality can be influenced to a considerable extent by choosing the most suitable needles and threads for the material to be sewn. It is recommended to use controlled GROZ-BECKERT needles system 1669 EEO only.

  • Page 20: Threading And Straight Grain

    Fig. 7 Threading and straight grain C A U T I O N ! Danger of injury! Switch off machine electrically and confirm that the machine is really in standstill position by operating the treadle for the motor control before threading. Otherwise danger of finger bruises and needle throughstitches.

  • Page 21: Thread Tension

    Thread tension Depending on thread and fabric quality, nature and thickness the thread tension is set by tension nut (1) ( Fig. 8). Thread take-up lever The thread take-up lever (2) Fig. 8 avoids thread twist and turning over of the loop, thus enabling a secure taking up of the loop by looper and needle.

  • Page 22: Cloth Retainer

    Cloth retainer A t t e n t i o n ! Danger of finger bruises through unintended actuation of the treadle during setting works in the needle plate area. The machine has no real cloth retainer. During the time of needle penetration the material is hold between hemmer and plunger.

  • Page 23: Sewing Material Transport

    Sewing material transport The machine transports the sewing material using a rigid upper transport. The feed (stitch length) can be set from 3 - 6 mm in 4 steps. Serially, a pyramid- toothed feed dog is mounted, which can be exchanged for a saw-toothed one if necessary.

  • Page 24: Adjusting The Top Feed

    4.8.2 Adjusting the top feed The transporter can be adjusted in its intrusion depth to the needle plate by loosening the two fastening screws. If the stitch length is adjusted across a greater range e.g., from 6 to 3 mm, then the feed dog should be readjusted. Adjustments might also be required when changing to sewing materials that are thicker or otherwise different in quality.

  • Page 25: Operating The Machine

    Operating the machine C A U T I O N ! Danger of injury! Please observe the sewing area carefully during sewing. Otherwise danger of finger bruises and needle throughstitches. Switching on Connect the compressed-air conditioner to the compressed air supplier (10 bar) or to the compressor and set it to 3 - 4 bar.

  • Page 26: Sewing Belt Loops

    Fig. 11 Sewing belt loops There is a number of hemmers available to sew nearly all required fabrics. In general, the belt loops are sewn of the waste fabrics of the trouser production. In the hemmer the fabric is symmetrically folded and centrically blindstitched. Using a tape facilitates the sewing and reinforces the belt loop.

  • Page 27: Setting Stitch Depth And Thread Tension

    Fig. 12 Attention: very fuzzy fabrics may disturb the process. The cuttings fall down into a garbage chute. The material is trimmed exactly and then guided to the hemmer. The tape is manually pushed through the bow at the swivelled down tape feeding device and then through the hemmer’s bow into the hemmer.

  • Page 28: Quick Hemmer Changing Device

    Quick hemmer changing device C A U T I O N ! Danger of injury! When working on the cutting system, switch off the power to the complete machine. Otherwise there is a danger of fingers getting crushed or cut! The hemmers are screwed to a holder and were set at works.
  • Page 29 Fig. 14 When the hemmer is exchanged, the height of the hemmer in relation to the curved knife needs to be checked and adjusted if necessary. Turn the knurled screw (1) for this until the correct setting has been made. BA_VEB100-7_A4_180618_en...

  • Page 30: Setting The Hemmer

    Setting the hemmer The hemmer lies on the plunger with the belt loop folded on one side already, i.e. that the fabric is hold for the needle penetration and the set stitch depth is ensured. Therefore the hemmer is slotted at the front part. The hemmer’s outlet should be approx.

  • Page 31: Fusible Tapes

    Fusible tapes It is recommended to provide the belt loops with a fusible tape. Choose the tape width according to the following chart: hemmer size tape width inch inch 8,5-9 5/16 7/16 10-10,5 Tapes of the most different qualities can be used. Tapes coated on one side only or on both sides are used with the fabric when pressing the ready sewn belt loop.
