Abstract
The present invention provides a pressure device to press a pair of members facing each other of a frame under the same pressure condition. A pressure device 5 for pressing top and bottom members 103 of a frame 101 for apertured grills, provided with a pair of pressure blocks 31 provided movably in the direction to bring the pressure blocks closer to and farther from each horizontal member 103 at the position facing to the top and bottom horizontal members respectively outside the frame 101, driving means 15 for moving synchronously each pressure block 31 in the direction to bring each pressure block 31 closer to and farther from each horizontal member 103, and pressure rolls 33 for contacting with each horizontal member 103 and supported on each pressure block 31, respectively.
Claims12
A pressure device for pressing a frame for apertured grills, which presses a pair of members facing each other of a frame for apertured grills comprising four members of top, bottom, right and left sides in the direction to bring said pair of members together, having:
- a pair of pressure blocks provided movably in the direction to bring the pressure blocks closer to and farther from said pair of members located at the position facing to said pair of members outside said frame,
- driving means for moving synchronously each said pressure block in the direction to bring each said pressure block closer to and farther from said pair of members respectively, and
- a plurality of pressure tips for contacting with said pair of members and screw adjustably supported toward and away from said pair of members on each said pressure block, respectively.
A pressure device for pressing a frame for apertured grills, which presses a pair of members facing each other of a frame for apertured grills comprising four members of top, bottom, right and left sides in the direction to bring said pair of members together, having:
- a pair of pressure blocks provided movably in the direction to bring the pressure blocks closer to and farther from said pair of members located at the position facing to said pair of members outside said frame,
- driving means for moving synchrionously each said pressure block in the direction to bring each said pressure block closer to and farther from said pair of members respectively, and
- a plurality of pressure tips for contacting with said pair of members and screw adjustably supported toward and away from said pair of members on each said pressure block, respectively, wherein said pressure tips are constituted with rolls rotatable on said pair of members.
A device for pressing a frame for constructing an apertured grill for a color selector of a color cathode ray tube, the frame including left and right vertical members and top and bottom horizontal members, comprising:
- pair of pressure blocks for opposing said top and bottom horizontal members and movable in a direction toward and away from said top and bottom horizontal members;
- driving means for moving said pressure blocks against said top and bottom horizontal members;
- said pressure blocks having a plurality of rollers mounted for pressing against said top and bottom horizontal members when said pressure blocks are moved toward said top and bottom horizontal members, wherein said rollers are arranged to roll along said top and bottom horizontal members during pressing of said pressure blocks against said top and bottom horizontal members.
