On.
The rolling press-wheel closes on the shaper between shaper and rubber-coated mechanism.
Optionally, the criss-cross skeleton includes four points of framves, and the recess is arranged on the end of point frame；The gluing
Mechanism includes：
Gluing frame, positioned at the corresponding outside for dividing frame, gluing frame is connected by pipeline with glue case；
Two glue brushes, one end and the gluing frame of each glue brush are fixed, and the other end stretches to corresponding recess on point frame；
Compression pump, for the glue in glue case to be painted by Pipeline transport to glue.
During work, skeleton and cover plate movement, compression pump paint the glue in glue case by Pipeline transport to glue, glue brush
Recess relative motion with dividing frame, while glue is applied on recess.
The beneficial effects of the invention are as follows：First spacing raised line, and each first limit convex are set in two side walls of mounting groove
The height of bar gradually changes along the radial direction of skeleton, so sets and can prevent to move effectively by line to limiting
Deformation so that line to the distance between keep it is more uniform and stable, improve the cross-talk resistant jamming performance of cable；Cover plate has two
Individual effect, first, waterproof cloth can be prevented to be embedded in mounting groove, influence data cable quality；Second, the second spacing raised line of cover plate
The position of line pair can be further limited, ensures line to position.
