Separating pressing force from the heating body lets booklet bonding run faster while reducing ceramic heater impact and extending service life.
A spring-backed pressing structure isolates impact from the ceramic heater, preserving bonding speed while extending heater life.
Selective heating raises adhesive toner rigidity near the heater, limiting transfer to booklet covers while preserving thermocompression bonding.
A shaped pressurization force profile helps one heating unit bond both large and small sheets evenly for more uniform booklet quality.
