Flexible flat round conductive cable and segmental calendering device for flexible flat cable

A segmental calendering device for a flexible flat cable, comprising:

• a framework, comprising:
• a left wallboard, with a left rolling chamber formed in the left wallboard;
• a right wallboard, with the right wallboard disposed opposite to the left wallboard, a right rolling chamber, corresponding to the left rolling chamber, formed in the right wallboard, the right rolling chamber having the same shape and size as the left rolling chamber;
• a supporting bar connected between the left wallboard and the right wallboard;
• and
• a frame roof, with a left end of the frame roof fixed to a top of the left wallboard, a right end of the frame roof fixed to a top of the right wallboard;
• a pair of left-rolling sliding guide mechanisms fixed opposite to each other within the left rolling chamber;
• a pair of right-rolling sliding guide mechanisms fixed opposite to each other within the right rolling chamber;
• an upper-calendering roller and a supporting mechanism of the upper-calendering roller, with the upper-calendering roller rotatably supported within the supporting mechanism of the upper-calendering roller and disposed above a position between the left wallboard and the right wallboard, the supporting mechanism of the upper-calendering roller sliding along the pair of left-rolling sliding guide mechanisms and the pair of right-rolling sliding guide mechanisms;
• a lower-calendering roller disposed below the upper-calendering roller correspondingly and rotatably supported between the left wallboard and the right wallboard;
• and
• a pressing mechanism for applying a pressure on the supporting mechanism of the upper-calendering roller and for adjusting the pressure, with the pressing mechanism disposed on the frame roof and connected to the supporting mechanism of the upper-calendering roller.
