A method for monitoring the quality of an adhesive application during a lamination process for manufacturing a packaging laminate comprising: conveying a first film or foil web (12) in a longitudinal direction (x), applying an adhesive material (14) over the whole surface or in a pattern onto the moving first film or foil web (12) and applying a second film or foil web (20) onto the adhesive coated first film or foil web (12) and conveying said first and second film or foil web comprising the intermediate deposited adhesive material layer (15) in the longitudinal direction (x) to a pressing station (22) to form a laminate (24). A fluorescent agent is added to and intermixed with the adhesive material such that an adhesive material comprising a uniformly distributed fluorescent agent is provided before the adhesive material (14) is deposited onto the first film or foil web (12). The fluorescent agent is chosen from those that absorb ultraviolet light and emit light in the visible spectrum. The fluorescence radiation emitted by the ultraviolet-exposed adhesive material layer (15) is detected by a visual inspection system (26) adapted to monitor the quality and homogeneity of the adhesive material layer (15).

The invention relates to a method, a calender and an apparatus for hot laminating a multilayer (6) comprising elastomeric ribbons (6', 6"') and a reinforcement ribbon (6") of a textile material having periodical splices (11). The multilayer (6) is laminated by a calender of a hot laminating apparatus, the calender comprising a pair of counter- rotating heated cylinders (1, 2) with parallel axes defining a lamination gap (5) therebetween, the height of which is controlled in a closed loop mode by a position control system comprising hydraulic actuators (7, 8) connected to a movable cylinder (2) of said pair of counter-rotating heated cylinders (1, 2). During lamination of the multilayer (6) a detection sensor (10) allows to detect incoming splices (11) of the reinforcement ribbon (6") upstream of the lamination gap (5). The control system is then switched from a position control mode to a pressure control mode, according to which the pressure in the supply circuit of the hydraulic actuators (7, 8) is adjusted independent of the height of the lamination gap (5). This control mode is maintained for the time a single splice (11) needs to cross the lamination gap (5) and the position control mode is restored after the passage of each splice through the lamination gap (5).

A description is given of a high-strength self-adhesive laminate cladding formed by a layered material, which comprises a cladding plate (2), an intermediate layer (3) of adhesive material, and a protective film (4), said cladding plate (2) being designed to make up the external, visible surface of the laminate cladding (1), whilst the protective film (4) is designed to be removed prior to use of the laminate cladding (1) in order to allow contact between the surface receiving the laminate cladding (1) and the layer (3) of adhesive material. Furthermore, a description is given of equipment (10) suitable for forming said laminate cladding (1) from a sheet of MDF or MDP and a two-sided-type adhesive.

The invention provides a wind turbine blade comprising a first shell (30), having a first bonding region, and a second shell (31) having a second bonding region, wherein the second bonding region of the second shell is bonded to the first bonding region of the first shell; and a temperature sensor (22) positioned between the first bonding region and the second bonding region. Having a temperature sensor (22) positioned within the turbine blade, in the region at which the two shells of the turbine blade are bonded together, allows for accurate determination and control of the temperature of the critical bonding regions during blade manufacture. The temperature sensor may be used during the service life of the wind turbine blade to detect delamination of the wind turbine blade.

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.
摘要:
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. lt has now been realised that the probability for unforeseen delays in the production line is decreased for each element in a batch onto which glue is applied. According to the present invention it has thus been found possible to further decrease the consumption o glue, without putting the quality in danger, by lowering the safety margin for each element in a batch.
