Abstract
Particleboard is manufactured by scattering an endless mat of chip and binder material on a series of overlapped mat carriers 17 moving on a forming conveyor 2 beneath a scattering station 1. A cut-off saw 5 is then used to separate the endless mat into mat sections 18 each of which is mounted on a respective mat carrier 17. The overlap between the mat carriers is eliminated and the laden mat carriers are removed from the forming conveyor 2 by an accelerating conveyor 6 which simultaneously operates as an intermediate store and a feed unit for a single storey press 8 arranged immediately after the accelerating conveyor 6. The accelerating conveyor 6 introduces the laden mat carrier into the inlet to the press from where it is transported into the press by internal transport devices of the press. After the mat section has been pressed to form a particleboard a pair of driven rollers 9 extract the mat carrier from the press and feed it towards a separating wedge 10. The mat carrier is deflected downwardly onto a conveyor 11 and the pressed board slides over the top surface of the separating wedge through further rollers 15. As soon as the mat carrier is fully located on a guide conveyor 11 beneath the separating wedge 10 the guide conveyor is pivoted downwardly and its direction of rotation is reversed so that the mat carrier can be transferred to a return conveyor 16. The mat carrier is then transferred back onto the forming conveyor from the return conveyor at a feeding station 14 which also serves to overlap the mat carrier with the preceding mat carrier and to turn the mat carriers over prior to them once again passing through the scattering station 1.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
