Single block drawing machines with capstan on horizontal axle, also known as horizontal bull blocks, are used to draw round and profile wires of steel and non-ferrous metals. Especially stress-free drawn cold heading wires up to the thickest avialable diameters may be produced in coils with weigh of max. 2500 kg either by collection
on a rotating carrier reel installed in front of the capstan or as coils spooled “turn by turn” an “layer by layer” in case of combination of drawing block with a spooling machine and use of collapsible spools.

Application
Mechanical design features
- Capstan driven by high-efficiency helical toothed spur gear, designed either as reduction or as switch gear for torque conversion, and vee-belt drive as connection to drive motor
- Central oil lubrication system with flow control and oil pump mounted outside of gear housing
- Capstan executed with:
- water cooling system with rotary coupling for water inlet and outlet in case of high drawing speeds respectively drawing of high carbon steel wire
- disconnectable capstan head for opening of pull-in dog and pulling out of wire without danger
- inclined pushing ring for drawing of any kind of profile wire or in case of skin passes
- rotating, swivel-mounted carrier reel for coil weight of max. 2500 kg, installed in front of capstan and in sound absorbing design
- single disc brake as safety brake for quick stop
- safety equipment according to German (UVV-Draht) and CE-Standard
Electrical design features
- AC main drive motors,
water – cooled = lownoise level and environment emission;
option:air cooling by individual fan - SIEMENS frequency converter, either water- cooled or air conditioner for entire switch cabinet
- stored – programm control SIMATIC S7
- Operator panel OP
