    General The FD 100 is suitable for packaging fats such as butter or margarine. The product is fed directly through a tube from the p rocessor. The machine wraps up to 1 20 pats a minute. The product passes from the feed section 5 into the moulding chambers of the moulding drum 6 , and is pushed by the moulding stamps pat for pat - together with the wrapping material cut­...

    3. 1 General The electrical system is represented in the separately supplied electric circuit diagram. The annexed key and the item numbers facilitate the reading of the circuit diagram. The following description of the "Operating elements " is de­ signed primarily as an aid for machine attendants. N 0 T E : The type and arrangement of the following operating elements is subject to possible alteration.

  • Page 27 7. 1 WRAPPING MATERIAL WEB To prevent the wrapping material reel from running on uncon­ trolled when the machine is stopped, the reel-off unit is equipped with a brake. Operating principle: On machine start, the wrapping material web overcomes the force in the torsion spring of the tensioner arm 3, and raises the latter .
  • Page 29 Doctor blade For various reasons the wrapping material (paper) tends to curl. To reduce the internal stresses, the wrapping material passes over the doctor blade 2. These stresses vary according to the nature of the wrapping material. Hence the variable setting of the doctor blade 2. High internal stresses: Steep doctor blade setting internal stresses:...

  • Page 31 End-of-reel monitor The end-of-reel monitor stops the machine when the wrapping material reel is empty. A perforated disc fitted to the end of the wrapping material guide roller activates an inductive proximity switch 2 in pulses. During wrapping material feed , therefore , the switch sends a certain signal to the electronic unit, which is tuned to this signal.

  • Page 33 7. 7 Photo-electric In order to position the pattern printed on the wrapping mate­ rial, the machine can be equipped with a photo-electric wrap­ ping material registration unit. The wrapping material must be provided with contrast marks, the spacing of which must agree with the print pattern repeat.
  • Page 34 7. 8 Figure 1 6 • The length of pull cut-off length plus 3 - is attained. The wrapping material knives close. The wrapping material portion is cut off . At the same time, the feed rollers open, the wrapping material is released. The pulse initiator cam of the proximity response switch closes.

  • Page 36 7 . 1 2 Mechanical wrapping material registration unit The mechanical wrapping material registration unit employs holes punched in the wrapping material instead of the printed contrast marks. When the feed rollers have advanced the wrapping material, the registration roller 3 sinks*, and pulls the web back between the opened feed rollers until it is stopped by the register pin 2, which engeges in the register holes.

  • Page 38 7.14 The cut-off length is governed by the size of the butter/mar­ garine pat. The length of pull of the wrap must be 3 - greater than the ultimate cut-off length, so that the wrapping material registration unit can function. ( Se e also chapter 7, "...

  • Page 43 7. 19 MOULDING DRUM • General The weight of the butter/margarine pats is governed by the volume of the moulding chambers in the moulding drum 3. The volume of the moulding chambers is in turn governed by the position of the moulding stamps 4. Forced into the moulding chamber from the feed system, the butter/margarine pushes the moulding stamp up until the guide roller 5 of the stamp contacts the adjustable cam segment 2.
  • Page 44 7.20 The weight alterations stated in this section are dependent on the pat size, and are therefore purely nominal figures. I 0 N C A U T The moulding stamps are fitted individually in the moulding chambers, and must therefore not be interchanged. Observe the markings.
  • Page 45 7.21 ®...
  • Page 46 7. 22 The stripper unit serves to separate the butter/margarine pat from the moulding stamp. Setting procedure: • Tension the stripper wire if necessary by tightening the knurled nut • The wire must sweep exactly along the face of the stamp, �d can be appropriately adjusted by slackening the lock screw 1 and turning the eccentric stud 2.

  • Page 49 7.25 Guide plate The guide plate 10 must be adjusted to suit the butter/mar­ garine pat. It must guide the finish-wrapped butter/margarine pat during the folder wheel rotation, without exerting pres­ sure on it. Presser station In the presser station the finish-wrapped butter/margarine pat is pressed, to give it an appealing appearance.

  • Page 53 7. 29 BUTTER / MARGARINE FEED SYSTEM Accumulator piston The butter/margarine feed system is equipped with an accumula­ tor piston 2. The purpose of this accumulator piston is to compensate the pressure fluctuations which are caused by the irregular extraction of butter/margarine by the moulding drum. The moulding drum is provided with four moulding chambers.

  • Page 55 7.31 Nozzle p late General: The nozzle plates of newest design are composed of (non-sprung) 18 mm thick plates (alu/teflon). The nozzle plate is set in the maker's works. If, after a certain period of production, butter/margarine exudes from between the moulding drum and the nozzle plate, the nozzle plate must be re-adjusted.
