Title: Steel band press for chipboards, etc. - has sensors which detect each band at entry and outlet ends and which are incorporated into band-adjusting mechanisms
IPC: B30B5/06
Filed: 1989-12-08
Abstract: For the prodn. of chipboards, fibreboards, laminates, etc. a continuous press is operated in the phases of idling, starting up, pressing and unloading. A continuously prepd. mat of material is moved into the press daylight and pressed at a set temp. and pressure, whereby both the upper and lower platens consist of continuous driven steel bands, each of which passes round a roller at each end of the press. Each band passes over a feed roller and, in the daylight area, over other rollers; each guide roller has control rams for cylinders which are adjustable; sensors are on both sides of the bands before the entry and outlet guide rollers concerned. They are additional sensors for the bands on each side of them at the point where they enter the daylight; these sensors together with the others function before the guide rollers (at least in the prodn./pressing phase), and their combined readings regulate the movement of the bands. ADVANTAGE - The design prevents the steel bands from running in an uncontrolled manner, at least in the prodn. phase, so that emergency stops no longer arise.
