摘要:
A joint detector detects a joint in an adhesive tape supplied from a tape supply section, and a computing unit determines a suitable cutting position of the adhesive tape for removing the joint in accordance with the detected results. A controller controls each mechanism to operate so as to satisfy the determined results by the computing unit. Thereafter, the adhesive tape including the joint is cut and removed.
摘要:
A method (600) for detecting and tracking a feature of a web of packaging material (102), using a first capacitor (106) placed at a distance (d) from the web of packaging material (102) is provided. The method (600) comprises; feeding (602) a section of the web of packaging material (102) to a first position (p), so that the section influences a dielectric property of the first capacitor (106), measuring (604), at a point of time (t), a capacitance of the first capacitor (106), and determining (612) the feature of the section passing the first capacitor (106) at the point of time (t), based on the capacitance.

摘要:
Intended is to eliminate failure in detecting the spliced portion of base paper sheet and malfunction of the detector in the corrugator line of corrugated cardboard. Also intended is to realize automated detection means for detecting the spliced portion improved in detection accuracy. A method for detecting a spliced portion where the leading end part of a second base paper sheet (50b) on standby is bonded to the trailing end part of a first base paper sheet (50a) in the course of being supplied and selectively removing corrugated cardboards containing the spliced portion in a corrugator line comprises; emitting an ultrasonic wave toward the base paper sheets (SC, FL) transferring and receiving the ultrasonic wave penetrated the transferring sheet in an upstream region of a cutting step, detecting change of attenuated quantity of the received ultrasonic wave as the sheet transfers, thereby detecting the spliced portion, and selectively removing corrugated cardboards containing the spliced portion as a faulty ones.
