KT calibration table

Mechanical structure

  • Height adjustment (vertical travel): There are different systems for height adjustment of the calibration tables that are selected by us depending on the calibration table and adjusted as required.
  • Longitudinal adjustment The longitudinal adjustment of a calibration table takes place either by moving the complete machine or by moving the tool carrier. Both variations are essentially possible, but they both have their advantages and disadvantages.
  • Traverse movement (moving perpendicular to the extrusion axis). Traverse movement normally takes place by moving the tool carrier. In part, additional ability to tilt the tool carrier is also required in this case. There are a variety of solutions for both movements that are selected according to the requirements.
  • Vacuum generator: All vacuum generators are mounted for speedy exchange or repair or maintenance work using sliding rails. Hose connections feature couplings. Electrical connection are designed as snap-in or screw connections.
  • Every calibration table requires a main water container. Depending on the water/vacuum system, the tasks of this tank are diverse. One task is the collection of the return feed water from all consumers of the calibration table, the disposal of the air extracted via the vacuum generators, and the return of return feed water to the operating water system. To minimise noise, the return feed lines of the vacuum generator are built into the tank in suppressing pipes. A ventilation tunnel is used to dispose of excess air, which simultaneously functions as a collective return feed. In order to clean the tank, a sufficient number of viewing windows are built in, which also serve as cleaning openings.
  • All attachments on the calibration table are laid out so that splashing water is caught and guided away as best as possible. The catching tray feature sufficient drains with large dimensioning. Multiple perforated metal inserts in the drains enable the draining water to be pre-filtered.
  •  Additional customer-specific attachments may be included in the design of the calibration table upon request.

RAZ caterpillar haul-off unit

Mechanical structure

  • Lower caterpillar unit fastened rigidly with the machine frame.
  • Upper caterpillar unit moves vertically via pneumatic cylinders and guided in a lengthwise direction as well as crosswise.
  • Adjustment of the pressing force or pressing counterforce of the upper caterpillar using precision pressure controllers. Separate activation of both pneumatic cylinders.
  • Both caterpillars are separately driven mechanically via one servo motor each with reduction gears. May be optionally regulated separately in case two frequency converters are used.
  • Lubrication of pre-tensioned double chains via central lubrication with manual operation (automatic lubrication optional).

BAV belt haul-off unit

Mechanical structure

  • Movement of belt units is possible via two methods:
  • Manually via a spindle with a left/right thread to move both transport belts parallel to the centre of the extrusion.
  • The lower belt unit is fastened in the machine frame and the upper belt unit is moved pneumatically. The belt unit features a rotating support to ensure optimal contact with the profile
  • Both belt units are separately driven mechanically via one servo motor each with reduction gears.
  • The top and bottom segments may be optionally regulated separately in case two frequency converters are used.

FA profile film applicator

Mechanical structure

  • Comfortable adjustment of the individual film units to the product contour.
  • In case of automatic film application, a second film applicator is switched to if the film roll of the first unit is used up. The used roll may then be replaced without interrupting production.
  • Upon request, the STEIN film applicator unit may be expanded with a rotating unit, which enables settings from 0 degrees (vertical) to 90 degrees (horizontal) without any stages.
  • The mounting mandrel for mounting the film roll may be adjusted to the size of the film roll cores that are used.

AK tilting table

Mechanical structure

Multiple variations are available for the tilt tables:

  • Support surface as folding chute with stainless steel sheets.
  •  Support surface as transport belt, folding.
  • Collection of the production profile segments in lateral catcher brackets, with or without support rollers.
  • Lateral push-off for profile segments on support arms (rigid or swivelling away). The support arms may also be designed as a single support or support roller.
  • Of course, during selection of a suitable tilting table, profile geometry, profile dimensions in the traverse cut and length, and other factors play a role.

PRO profile stacking machine

Basic mechanical layout

  • With regard to the transport belts that pull the profiles into the machine, durable, enhanced woven belts with surfaces that are as smooth as possible.
  • Rotating device (turning mechanism): The rotating device usually comprises a motorised toothed wheel with integrated pneumatic grippers. During the work process, the profile is gripped by the grippers on one end and lifted from the transport belt. The lifting is supported by a special device on the other end of the profile, in which case the profile
    length is able to be turned freely above the belt.
  • The support arms consist of stainless steel profiles with profile grooves. The actual support for the profiles is pulled into the top profile groove. This support consist of PTFE sliding material and may be replaced easily in case of wear.
  • The traverse slide device consists of an aluminium profile arranged on the side of the transport belt, which simultaneously acts as a lateral guide as the profiles run into the machine. The sliding movement is executed pneumatically or by a motor.
  • The clamping traverse for handling the profile layers may be set for the standard version for profile lengths between 5500 and 6500 mm. The clamping jaws are laid out accordingly for handling sensitive profiles.
  • Cassette fastening: To fasten the transport cassettes in the stacking area, the cassette is normally gripped by clamp grippers and the sides of the cassette are pulled outwards, provided they are stable enough to permit this. This ensures sufficient space for a secure depositing process, even if a protective film is also inserted into the cassette. Cassettes
    may also be gripped from underneath and fastened to a lateral guide. Both systems are often used, since different cassette systems may also be used.
