Haul-offs

Haul-offs for smooth and corrugated pipe

Haul-offs for the corrugated pipe extrusion process

Haul-offs for corrugated pipes of between 40 and 1400 mm diameter. Machines equipped with two or three tracks for synchronized pulling with the corrugator speed. The haul-offs are installed on the extrusion line to avoid any buckling to the corrugation after their exit from the corrugator.

DSCF3513-780x439

Advantages

  • Compact but powerful machines
  • Top quality encoder to achieve the perfect synchronization with the corrugator
  • Robust welded steel frame to eliminate vibration
  • Leading brand components
  • Simple-to-read controls in local language
  • Accurate speed control from very slow to very fast
  • Hard-wearing, long-lasting belts
  • Simple height adjustment

Technical features

  • Strong, sturdy frame
  • Top quality materials used and leading components in construction
  • Machine easily movable between production lines
  • Precise pipe guide system
  • Extremely versatile, safe and reliable

Haul-Offs for Smooth Pipes

Haul-offs for smooth plastics pipes with belts or pads made to obtain the maximum pulling force and contact pressure on the pipe. Poly-v belts caterpillar tracks with contact surface made up of rubber or special materials or caterpillar tracks with vulcanized rubber inserts, which can be changed over for different profiles.

Tracks controlled by means of motors equipped with encoder, which ensure accuracy, stable extrusion speed and reduced maintenance. The fine adjustment of the upper belt guarantees the best traction, avoiding any crushing effect on the pipe. The Haul-offs are equipped with on-board digital extrusion speed indicators.

Advantages

  • Perfect adherence to the pipe
  • Accurate speed control
  • Hard-wearing, long-lasting belts and pads
  • Easy height adjustment
  • Quick pads changeover

Technical features

  • Strong, sturdy frame
  • Top quality materials and leading components used in construction
  • Machine easily movable between production lines
  • Accurate pipe guiding system
  • Extremely versatile, safe and reliable

Options

  • Remote control
  • Custom built machines available upon request

Cutting units for plastic pipes

All our machines are manufactured upon customer’s request to match different types of extruded plastic products. For this reason, our devices are able to process PVC, PE, PP and LDPE, corrugated and smooth, single or double wall pipes.
Each unit is compatible with automatic in-line operation, including electronic synchronisation with the line.

Cutting Devices Types

  • For in-line (TVP) or off-line (TC-TVP) production
  • Cutting device automatically finds the corrugated pipe groove centre (TVP-C)
  • Shearing cuts for copper pipes with closing of both ends (TPE)
  • Disks or planetary knife cutting techniques

  • High-speed and accurate cutting
  • Energy saving
  • Versatile units customizable according to the application field
  • Leading brand components
  • Customised software according to customer needs
  • Reduces production waste and costs
  • Easy use and maintenance

Technical features

  • Strong, sturdy frame
  • Machine easily movable between production lines
  • Precise pipe guide system
  • Vision sensors for precise cutting process (optional, depending on the application)
  • Units available with independent brushless motors for maximum system flexibility
  • Cycle time control for production optimisation
  • Planetary units equipped with universal pipe locking clamps

Rapid Planetary Cutting unit type TVP

TVP family consists of TVP for smooth pipes and TVP-C for corrugated pipes. TVP is a planetary saw with orbital cut for PVC-PP pipes, up to diameter 200mm for corrugated ones. During the cutting phase the cutting unit follows the pipe at the extrusion speed.

The cut is executed by a blade rotating on the pipe circumference, without material removal. The cut is consequently clean without burrs or swarfs. The TVP saw can be equipped with an encoder system to execute “at once” cuts synchronized to the extrusion speed.

TVP-C

TVP-C is a rapid planetary cutting unit only for corrugated pipes. The difference with the TVP is the automatical capacity of the TVP-C cutting unit of finding the corrugated pipe groove centre.

TC.TVP/40

The range of machines built by Baruffaldi Plastic Technology-Primac has been enriched with the new TC.TVP/40 planetary cutter with built-in traction haul-off, for the in-line cutting and processing of PP, PE and LDPE pipes.

The device has rotary knife cutting without material removal, with cutting precision of ±1 mm/m at high process speed (20 m/min).

The cutting system is equipped with vision sensors for precise point cutting points on the moving profile. The haul-off group, with two independent track speed pairs, provides for pipe compacting where necessary. Haul-off and cutting units are operated by four independent brushless motors for maximum flexibility of the system.

The last generation operator panel allows the user to select production programs through preset job prescriptions. The advanced electronics of this new, versatile and compact machine makes it possible to control cycle times in order to optimize the production process at best. The machine is also distinguished by its quiet operation and energy saving features.

Knife-cutting unit type TPE

Knife cutter for the automatic cutting of HD-PE, LD-PE and PP pipes as well as copper-pre-insulated PE pipes on the extrusion line.

The unit is designed to cut different pipes and profiles by replacing easily the pipe clamping vices. The cutting unit is assembled on a carriage that follows the pipe path during the cutting phase.

The blade is controlled by an hydraulic system.
The cutting blade penetration and the truck feed are adjustable from the outside of the machine and they are controlled by a pneumatic cylinder.
