The stationary capstan take-up frames are typically used to take-up annealed and galvanized low carbon wire, patented and phosphated or galvanized high carbon wire and annealed stainless steel.
This system can also be utilized to take-up hard drawn low and high carbon wire.
The machine frame consists of sections of heavy duty fabricated construction bolted together. The sections are supported by robust steel structures.
The upper side of the frame, completely covered with steel plates and provided with handrails, forms a convenient platform for stringing-up and maintenance purposes.
The capstans are normally manufactured of special steel and are hardened at the wire line surface. The capstans are on vertical axis and bolted to the frame.
The winding arms are of heavy duty solid steel plate providing a secure mounting for the guide sheaves and the straighteners. All guide sheaves and straighteners are adjustable for wire casting purposes.
Each winding arm can be operated individually and is driven, through a toothed belt and pulleys, by an AC geared motor with frequency inverter
The main advantage of this type of take-up, is the possibility to obtain pattern laid coils. This is achieved by rotating at very low speed an inclined turntable, carrying the carrier. The pattern laid package produces significantly increased coil weights and reduces snarls in the subsequent pay-off process.
They are equipped with a double straightening unit and can be supplied in various sizes starting from 300 mm in diameter up to 760 mm. The capstan can either be V groove or flat type depending on the application. The stationary versions are equipped with accumulation arms and with a motorized trolley. The trolley can be operated pneumatically to extract the coil from under the flyer.
These can also be supplied in double deck arrangements such as 350/550 and 400/600.

The rotating capstan take-up frames are typically used to take-up hard drawn and galvanized low or high carbon wire, large diameter annealed and galvanized low carbon or patented high carbon wire, annealed stainless steel wire with drawing possibility and oil tempered wire.
The use of a rotating capstan take-up is essential under one or more of the following conditions:
Large wire diameters, up to 8mm
Tensile strength over 1500 MPa (213 000 psi)
Twist unacceptable in the finished product.
The machine frame consists of sections of heavy duty fabricated construction bolted together. The sections are supported by robust steel structures.
The capstans are normally manufactured of special steel and are hardened at the wire line surface.
Each capstan can be operated individually and is driven, through a toothed belt and pulleys, by an AC geared motor with frequency inverter.
Rotating type take-ups: These rotating coilers are used to produce coils of wire without twist. The coil itself rotates at the same speed of the capstan and winds the wire in the form of a coil. These units are equipped with a special arm that positions the wire wraps in a pattern-laid looking manner and can be supplied with capstan sizes starting from 300 mm up to 760 mm .
