Method of manufacturing printing and embossing type elements

A method of manufacturing type comprising steps of:

• supplying a portion which will serve as a typeface with a prescribed amount of a granular heat-curable resin consisting of particles of a first size having a hardness capable of withstanding pressure applied at embossing and a particle size affording smoothness after molding;
• supplying a portion which will serve as an impact face with a prescribed amount of a granular heat-curable resin brought into adhering contract with the granular heat-curable resin of the first particle size and consisting of particles of a second size larger than the first size and having a hardness capable of withstanding pressure applied at embossing and an elasticity capable of withstanding and of absorbing impact sustained at embossing after molding;
• heating the granular heat-curable resin in superimposed form;
• and
• applying predetermined amount of pressure at predetermined number of times on the granular heat-curable resins in superimposed form during said heating so that an intermediate joint layer made from a mixture of the granular heat-curable resins of the first and second size is created in enough thickness at a continuously and gradually changing mixing ratio, between the portion which will serve as a typeface and the portion which will serve as an impact face.

• heating the granular heat-curable resins in superimposed form;
• and
• applying predetermined amount of pressure at predetermined number of times on the granular heat-curable resins in superimposed form during said heating in cooperation with impact absorbing means for absorbing applied pressure so that an intermediate joint layer made from a mixture of the granular heat-curable resins of the first and second size is created in enough thickness at a continuously and gradually changing mixing ratio, between the portion which will serve as a typeface and the portion which will serve as in impact face.

A method of manufacturing type elements for printing and embossing comprising the steps of:

• filling a type element mold by
• supplying a first portion of an embossing typeface element which will serve as a typeface for embossing with a first prescribed amount of a granular heat-curable resin consisting of particles of a first particle size having a hardness capable of withstanding pressure applied at printing and a particle size affording sufficient smoothness after molding to form a typeface surface to the element being manufactured, and
• supplying a second portion of material for said type element being manufactured which will serve as an impact absorbing portion of said type element by supplying a second prescribed amount of a granular heat-curable resin to be brought into adhering contact with the granular heat-curable resin of the first particle size, said second prescribed amount of granular heat-curable resin consisting of particles of a second particle size larger than the first particle size and having a hardness capable of withstanding pressure and hammering of the type element which will be applied during printing and embossing action of the said type element and having after molding an elasticity capable of withstanding and of absorbing impact sustained during a printing or embossing action;
• and
• heating the granular heat-curable resins in said mold in superimposed form;
• and
• applying predetermined amount of pressure at predetermined number of times to the granular heat-curable resins in superimposed form during said heating to form an intermediate joint layer between layers of first particle sized materials and said second particle sized materials made from a mixture of the granular heat-curable resins of the first particle size and the second particle size which is created with enough thickness so as to maintain integrity of the type element during subsequent repeated printing and embossing action of said type element and with a continuously and gradually changing mixing ratio between materials, between the portion which will serve as a typeface and the portion which will serve as an impact portion.
