  • Fig. 6a-c schematically illustrate three embodiments of some side projections of the inventive non-planar suspended ceiling. Note that the profile assembly is not shown in Fig. 6a-c .
  • Fig. 6a illustrates side projections of a sawtooth-shaped suspended ceiling 300 wherein each ceiling tile 100 is arranged at an angle ⁇ with respect to the horizontal plane H.
  • the first side edges 102 of the ceiling tiles 100 are concealed.
  • the second side edges 104 of the ceiling tiles 100 are exposed and are formed at right angles with respect to the front sides 112 of the ceiling tiles 100.
  • the second side edges 104 are parallel with each other.
  • Fig. 6b illustrates side projections of a sawtooth-shaped suspended ceiling 300 wherein each ceiling tile 100 is arranged at an angle ⁇ with respect to the horizontal plane H.
  • the first side edges 102 of the ceiling tiles 100 are concealed.
  • the second side edges 104 of the ceiling tiles 100 are exposed and are arranged perpendicularly to the horizontal plane H.
  • the second side edges 104 are parallel with each other.
  • Fig. 6c illustrates side projections of a suspended ceiling 300 having a profile in the form of a triangle wave wherein the ceiling tiles 100 have an opposed inclination with respect to the horizontal plane H. More specifically, the adjacent ceiling tiles 100 are arranged at angles ⁇ and - ⁇ , respectively, with respect to the horizontal plane H. The first 102 as well as the second 104 side edges of the ceiling tiles 100 are concealed.
  • Fig. 7 there is illustrated a side view of a device 400 for manufacturing of the inventive ceiling tile 100 according to one embodiment. It is understood that the objects in Fig. 7 also have extensions in a third direction, i.e. in a direction perpendicular to a plane of the drawing in Fig. 7 .
  • the device 400 is arranged to receive a ceiling tile material 500 at a feeding station 412. Moreover, the device 400 comprises a receiving surface 410 which is arranged for reception and transportation of the ceiling tile material 500, thereby forming a transport path and a transport direction R for the ceiling tile material 500 between the feeding station 412 and an output station 414 located downstream of the feeding station 412.
  • the transport direction is indicated by an R in Fig. 7 .
  • the receiving surface 410 is constituted out of a transport conveyor belt and the ceiling tile material 500 is kept in contact with the receiving surface 410 throughout its transport from the feeding station 412 to the output station 414 by means of the gravitational force, whose direction is indicated by a G in Fig. 7 .
  • the ceiling tile material 500 may be kept in contact with the receiving surface 410 by means of a holding device.
  • the device 400 further comprises a groove-forming station 420 which is arranged to provide one or several grooves 510in the ceiling tile material 500. Since the receiving surface 410 is movable and the groove-forming station 420 fixedly mounted, the ceiling tile material 500 may be displaced relatively to the groove-forming station 420.
  • the groove-forming station 420 comprises a circular cutting device which partly extends into the transport path for forming the groove 510 in the ceiling tile material 500 which passes by the groove-forming station 420.
  • a partitioning device 440 is located before the output station 414 in the transport direction R, downstream of the groove-forming station 420.
  • the partitioning device 440 is arranged to partition the ceiling tile material 500 into predetermined sizes according to well-known methods for a person skilled in the art; for example, the ceiling tile material 500 may be partitioned intermittently or continuously. Note that only a part of the partitioning device 440 is shown in Fig. 7 . According to the present embodiment, the partitioning device 440 comprises a cutting device 442. Lastly, the output station 414 is arranged downstream of the partitioning device 440.Next, the manufacturing method of the ceiling tile 100 according to the present embodiment will be described. First, a ceiling tile material 500 of a given thickness and width is feeded into the device 400 at the feeding station 412 and placed on the receiving surface 410.
  • a surface corresponding to a back surface of the ceiling tile 100 to be produced is placed on the receiving surface 410.
  • the ceiling tile material 500 is cut into an appropriate width and thickness before it is fed into the device 400.
  • the ceiling tile material 500 is feeded towards the output station 414 along the transport path in the transport direction R.
  • the ceiling tile material 500 passes by the groove-forming station 420 which is located on a right side of the ceiling tile material 500 in the transport direction.
  • the groove-forming station 420 arranges a groove 510 in the ceiling tile material 500 in a second side edge 504 (the first side edge is not shown in Fig. 7 ) by means of the circular cutting devices as explained above.
  • the groove 510 is arranged at a distance D 2 from the receiving surface 410, and hence also from the back surface, as indicated in Fig. 7 .
  • a groove may be provided in the first side edge (not shown) of the ceiling tile material 500 on an opposite side of the second side edge 504.
  • the groove in the first side edge is preferably provided at a distance D 2 from the receiveing surface 410, and hence from the back surface, where D 2 is different from D 1 .
  • the ceiling tile material 500 may be rotated 180° around an axis extending in a normal direction with respect to the back surface and may then placed on the receiving surface 410, whereby the groove-forming station 420 may provide the groove also in the first side edge.
  • an additional groove-forming station e.g. placed on a left side of the ceiling tile material 500 in the transport direction, may provide the groove in the first side edge.
  • the ceiling tile material 500 is partitioned into ceiling tiles 100 at the partitioning device 440 which thereafter are transported along the transport path to the output station 414.
  • the ceiling tile material 500 comprises a groove 510 along a part of its side edge 504 while the ceiling tile 100, which has passed the groove-forming station 420 completely, comprises a groove 130 along its entire side edge 104.
  • the ceiling tiles 100 may be further processed. For example, they may be provided with rounded edges, chamferings, colouring, auxiliary equipment in the form of a metal strip, a LED light assembly, a décor, a sensor array or a speaker arrangement, a lighting device in the interior of the ceiling tile 100, undulations in the some of the side edges, etc.
