  • Roll holder, particularly for a rolled flat product
    Patent number: 4556160
    Abstract: A roll holder includes a base plate and two yokes pivotally supported on the base plate. One of the yokes is a suspension yoke having a free arm for holding a roll with a tape material thereon and another yoke is a braking yoke for braking the rotation motion of the roll when a portion of the material is to be torn-off from the roll. The braking yoke also has a free arm which overlaps the free arm of the suspension yoke and has a U-shaped cross-section so that the free arm of the suspension yoke without the roll thereon can be inserted into the free arm of the braking yoke and the roll holder can be folded.
