Claims14
A method of making a guide device for printer needles used in printer heads of mosaic printers, such guide device being adapted to guide the needles adjacent to the printing area of a printing head, the method comprising:
- providing members of rolled or drawn material;
- stamping or embossing guide grooves in said members;
- forming openings in said members across said grooves to interrupt the grooves so that the grooves provide spaced aligned sections;
- assembling said members with said guide grooves in complementary cooperaing confronting relation and thereby forming needle guideways;
- and
- securing the members in assembly to provide said device.
A method of making a guide device for printer needles used in printer heads of mosaic printers, such guide device being adapted to guide the needles adjacent to the printing area of a printing head, the method comprising:
- providing members of rolled or drawn material;
- stamping or embossing guide grooves in said members;
- surface hardening the members in the grooves to assure wear-resistant bearing surfaces in the guideways defined by the grooves;
- assembling said member with said guide grooves in complementary cooperating confronting relation and thereby forming needle guideways;
- and
- securing the members in assembly to provide said device.
A method of making a guide device for printer needles used in printer heads of mosaic printers, such guide device being adapted to guide the needles adjacent to the printing area of a printing head, the method comprising:
- providing members of rolled or drawn material;
- stamping or embossing guide grooves in said members:
- assembling said members with said guide grooves in complementary cooperating confronting relation with gauging and indexing pins in confronting grooves, and thereby forming needle guideways;
- then securing the members together to provide said device;
- and removing the pins to receive printer needles in the guideways.
A method of making a guide device for printer needles used in printer heads of mosaic printers, such guide device being adapted to guide the needles adjacent to the printing area of a printing head, the method comprising:
- providing members of rolled or drawn material;
- stamping or embossing guide grooves in said members comprising corrugating said members to provide said grooves in staggered relation on opposite faces of the members;
- providing the members with indexing means;
- indexing and assembling a plurality of the members with the grooves in matching relation and thereby providing a plurality of rows of needle guideways with the guideways staggered in contiguous rows;
- and securing the members in assembly to provide said device.
A method of making a guide device for printer needles used in printer heads of mosaic printers, such guide device being adapted to guide the needles adjacent to the printing area of a printing head, the method comprising:
- providing metal panel members of rolled or drawn material;
- stamping or embossing guide grooves in staggered relation in the opposite faces of said members;
- assembling a plurality greater than two of said members with said guide grooves in complementary cooperating matching relation and thereby providing a plurality of rows of needle guideways with the guideways staggered in contiguous rows;
- and securing the members in assembly to provide said device.
A method of making a guide device for printer needles used in printer heads of mosaic printers, such guide device being adapted to guide the needles adjacent to the printing area of a printing head, the method comprising:
- providing metal panel members of rolled or drawn material;
- stamping or embossing shallow guide grooves on one face of each of the panel members and with the grooved area of the face of each of the members offset relative to opposite end portions of the members;
- assembling said members with said guide grooves in complementary cooperating matching relation;
- assembling said opposite end portions of the members together and thereby maintaining said areas properly spaced apart so that said guide grooves form needle guideways;
- and securing said end portions together.
