OTO strip joiners
Built with ample engineering safety factors and precision-machined components, our strip joiners are conceived to provide a precise and dependable weld operation and consequently optimize mill uptime.
Covering a range from 30 to 1,300mm wide and 0.3 to 16mm thick metal strip, Fives' strip joiners offer convenient solutions to numerous tube manufacturing applications.The main line of automatic machines (GG) is provided with control of strip end position, feed into the clamps, trim of strip ends, weld cycle, bead milling, and release. All functions are automated and integrated in the machine PLC. Machine layout is ergonomically designed to simplify weld inspection by operator.
All strip joiners are designed to withstand many years of use in the most demanding applications with minimal maintenance.
AUTOMATIC STRIP JOINER GG SERIES
Automatic strip joiner GG series allow to join the leading end of the new strip with the trailing end of the strip currently on the tube mill.
A twin blade guillotine shear (one blade for the end of the outgoing strip and the other for the end of the incoming strip) performs precision shearing of the strip ends to prepare the edges for the subsequent welding operation. The weld bead could be removed by an optional milling unit. The trimming and welding cycle can be selected in one of the following ways:
- Semiautomatic (automatic trimming, manual welding)
The automatic cycle can be suspended at any point to perform any manual operations that may be necessary, and then resumed either automatically or manually. An independent control desk provides the facility to select the required cycle and supervise correct execution of the operation.
AUTOMATIC STRIP JOINER GAL SERIES
Automatic strip joiner GAL series executes the outfeeding strip junction with the mill infeeding strip. A single blade shear (the same shear used for the outfeeding strip tail and for the infeeding strip head) executes a precise shearing of the strip edges; this allows an improved prearrangement of the edges for the following welding. The welding bead is not removed, as it does not interfere with the following strip filling and profiling phases. The strip joining and welding cycle can be carried out in one of the following modes:
- Semiautomatic (the strip joiner automatically stops at each phase, and the cycle continues only after the operator confirmation).
The automatic cycle can be interrupted in any moment, in order to carry out any manual operation: the cycle can then be restored in automatic, semiautomatic or manual mode. An independently operated control console allows the selection of the required cycle and the control of the correct cycle execution
MANUAL STRIP JOINER GH SERIES
Manual strip joiner series, with facility to translate the unit offline, are very simple and make it possible to perform trimming and joining of the trailing and leading ends of strip correctly and rapidly.
The ease of use and practical nature of the controls recommend the use of this machine in place of more conventional entirely manual strip joiners. The strip joiner assembly can be divided into two areas:
- A lower zone where shearing of the leading end and trailing end of strip takes place.
- An upper zone where the leading and trailing ends are welded.
A positioner in the upper zone allows the welding operation to be executed automatically.
IN-LINE MANUAL STRIP JOINER GM SERIES
This very simple and compact assembly makes it possible to perform trimming and joining of the trailing and leading ends of strip correctly and rapidly. The ease of use and practical nature of the controls recommend the use of this machine in place of more conventional entirely manual strip joiners. The strip joiner assembly can be divided into two areas:
- An initial zone where shearing of the leading end and trailing end of strip takes place.
- A second zone where the leading and trailing ends are welded.
In the first zone pneumatic clamps are used to clamp the strip trailing end and then the strip leading end in order to perform the shearing operation in total safety. When the trailing and leading ends of the strip have been cut they are positioned and clamped against the copper backplate by means of the pneumatically controlled welding clamps. A system of guides makes it possible to align the leading and trailing ends of the strip before the cutting and welding operations.
The welding is manual, through an external welding unit.
