Abstract: The invention relates to a portable vocal booth (1) comprising a hood (2) that comprises a top (3), side walls (6), a front wall (4) and a rear portion (5) and is adapted to freely enclose a singer's head. The hood (2) comprises a rear part (R), which is intended to accommodate the singer's head and is open forwards and downwards and otherwise limited by the top (3), the side walls (6) and the rear portion (5), and a front part (F), which is intended to be in front of the singer's head and at the back is open towards the rear part (R) and is otherwise limited by the top (3), the side walls (6), the front wall (4) and a bottom wall (8), wherein a sound absorbing insert (16) is provided in the front part (F) inside the front wall (4). In the front part (F) between the sound absorbing insert (16) and the rear part (R) of the hood (2) a partition wall (17) of a sound absorbing material is arranged, and between the sound absorbing insert (16) and the partition wall (17) a gap (18) is provided.

Abstract: The invention relates to a method of manufacturing a composite product, wherein a plurality of elements are assembled by gluing them together under pressure, the method comprising applying glue to at least one surface of each element on which glue is to be applied, assembling the elements to a desired structure and subjecting the assembled elements to pressure in a press, which method further comprising controlling the amount of at least one component of the glue applied. However, if unexpected delays occur in the production line, there is a risk that the waiting time for the elements of a batch on which glue already have been applied will be too long and gluing thus defective. As defective gluing means both loss of production and waste of material it has been found advisable to keep a reasonable safety margin and apply more glue than in the ideal case will be necessary. On the other hand, in cases there are no unexpected delays, this practice leads to use of more glue than necessary.

Abstract: The invention relates to a method of manufacturing a composite product, wherein a plurality of elements are assembled by gluing them together under pressure with a glue comprising at least one first component and at least one second component, which method further comprises controlling the relation between the second and the first components of the glue applied. The press time is often a limiting factor for the production capacity of a plant and renders the production planning difficult. The press time is affected not by the temperature of the elements, but also a great extent by the relation between the components in the glue and can be significantly decreased by increasing the amount of hardener compared to the amount of resin. According to the invention, it has been found that this can be utilised for controlling the gluing in a way so the production can be planned more efficiently.
