  1. Leister Uniplan-E

    Leister Uniplan-E
    The Leister UNIPLAN-E reputation is second to none when it comes to welding PVC coated or reinforced materials such as those used in making PVC banners, lorry tarpaulins, manufacturing marquee's or inflatable structures such as tennis domes or sports hall coverings; in fact the Leister Uniplan E is so versatile that it forms the core basis machine for several other of the Leister automatic welding machine range.
  2. Leister Uniplan Roof (110V)

    Leister Uniplan Roof (110V)
    The original compact, light and powerful 110V automatic hot air welding machine designed for welding roof membrane; the UNIPLAN Roof will bring more consistency to welding single ply roof membrane and is the natural partner to the TRIAC on the roof.
  3. Leister Uniroof E 110V

    Leister Uniroof E 110V
    The most recent addition to the range of single ply membrane roof welding machines, the Leister Uniroof 110v ensures a consistent 40mm overlap weld particularly for smaller installation areas, or in areas that are technically confined but still need to meet the technical requirements of 40mm.
  4. Leister Uniroof E 240V

    Leister Uniroof E 240V
    The latest in the range of Leister single ply membrane roof welding machines, the Leister Uniroof 240v ensures a consistent 40mm overlap weld particularly for smaller installation areas, or in areas that are technically confined but still need to meet the technical requirements of 40mm. Based on the design of the already well established 110v Uniplan Roof,(still current) the Uniroof provides more power and therefore welds more metres per minute when welding plastic membrane.
  5. Leister Variant-T1 (Anti-Vandalism)

    Leister Variant-T1 (Anti-Vandalism)
    Used for welding reinforcement and anti-vandalism tapes in vehicle tarpaulins and lorry side curtains. The Variant T1 boasts an impressive welding speed of up to 18 metres per minute, combined with a slim, study and compact design.
