BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to an apparatus for the manufacture of insulating chutes, of mineral wool in particular, comprising means for winding plies of an insulating material on to cores; means for curing the insulating material wound on the cores; means for removing the cured insulating material from the cores; and means for feeding empty rolls into said winding means.
Attempts have been made for a long time to make apparatuses of this type operate continuously and as automatically as possible. In one way or another, cores have been fed at an even rate into the winding means and further through a furnace-like curing means. The curing of an insulation, which could be compared to baking, takes place slowly, wherefore the curing furnace is very large and expensive and causes further problems as the cores have to be removed from within the insulations in order to be returned to the winding means.
SUMMARY OF THE INVENTION
The object is to provide a new apparatus for the manufacture of insulating chutes, which apparatus is simpler and more efficient than previous apparatuses.
The apparatus according to the invention is mainly characterized in that the cores are arranged in groups on an endless transporter; that the transporter comprises, between the groups of cores, empty spaces corresponding to the number cf cores in each group; that the transporter is arranged to move step by step a distance corresponding to the interspace between individual cores in a group when the first core in each group reaches the winding means, and a distance corresponding to the interspace between the groups when the last core in each group leaves the winding means; and that the means for curing the insulation are arranged to cure one group of cores at a time so that it detaches the entire group from the transporter, effects the curing, and returns the group into the empty space ahead of the following group of cores on the transporter.
Means for coating and splitting the insulation are preferably positioned after the curing means, which coating and splitting means operate in synchronization with the winding means so &hat the position of the groups of cores relative to each other remains unchanged all the time, and the apparatus can operate continuously and automatically.
The curing of the insulation in each group of cores is preferably carried out by simultaneous application of compression and hot air.
In a preferred embodiment of the apparatus according to the invention, each core is detached from the transporter for the time of the winding and is thereafter returned to the transporter, whereby even insulating chutes varying greatly in thickness can be wound on to a core without interfering with the overall operation of the apparatus.
In the following the invention will be described in more detail with reference to the attached drawing.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a schematical side view of an apparatus according to the invention.
FIGS. 2 to 4 show a preferred embodiment of core supporting means included in the transporter of the apparatus.
FIG. 5 illustrates the detachment of cores from the transporter and returning the same to the transporter at the winding means.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
In FIG. 1, the reference numeral 1 designates an endless transporter which moves around in a vertical plane via two idler wheels 2 and 3 and which may comprise two parallel chains provided with supports for detachably supporting cores 12 at both ends thereof. The reference numeral 4 designates means for winding a ply of an insulating material on to a core 12; 5 designates means for curing the insulating material; 6 designates a coating means; and 7 designates means for removing the core and for splitting the insulation into a chute.
Three successive cores 12 form a group, and an empty space 8 corresponding to three cores is left between two successive groups on the transporter 1.
When the first core 12 in a group of cores reaches the winding means 4, as shown in FIG. 1, the
