Abstract: In a rotary stamp with master stamp incorporating a master stamp having an oblong hole from which a desired print section of a rotary stamp is exposed in the bottom part of a grip case containing the rotary stamp, a thin melt-processed laminated belt produced by treating the superficial layer of a laminated belt foundation composed of porous thermoplastic resin belt base and an ink circulation reinforced rear fabric such that only a print section is left in a porous state while the other part of the belt is melt processed into anon-porous state that is used as an endless print belt, with the oblong hole in the master stamp formed in a size which allows the belt to pass along a bridge part without the surfaces making contact therewith.

Abstract: An endless print belt for rotary stamp in which a plurality of print sections are disposed and spaced-out between each other on a surface of a print belt main body, with at least the print surface of the print section being formed of porous material, wherein a groove in the width direction is formed at an intermediate position of each spaced-out part. Preferably, the spaced-out part is formed such that the surface thereof is in a non-porous state and both ends of the groove are formed into a bund part, for preventing ink from running out.

Abstract: In a rotary stamp with master stamp incorporating a master stamp 3 having a window hole 30 from which a desired print section of a rotary stamp 2 is exposed in the bottom part of a grip case 4 containing a rotary stamp 2, a thin melt-processed laminated belt produced by treating the superficial layer of a laminated belt foundation composed of porous thermoplastic resin belt base 24a and an ink circulation reinforced rear fabric 24b such that only a print section is left in porous state while the other part is met-processed into non-porous face is used as an endless print belt 24 and the window hole 30 in the master stamp 3 is formed in a size which allows the belt to pass through along a bridge part 23 without its surface's making contact therewith.

Abstract: An endless print belt for rotary stamp in which a plurality of print sections 5 are disposed with spaced-out parts 51 between each other on the surface of a print belt main body 24 at least the surface of which is formed of porous material, wherein a groove 25 in the width direction is formed at an intermediate position of each spaced-out part 51. Preferably, the spaced-out part 51 is formed such that the surface thereof is in non-porous state or both ends of the groove 25 are formed into a band part 53 for preventing ink from running out.
