Abstract

The present disclosure relates to manufacturing an inflatable structure. There is determined one or more contours of at least a portion of an inflatable structure to be manufactured. There is further provided a drop stitch fabric having a first layer and a second layer tethered by drop stitches. Moreover, there is provided along at least a portion of the drop stitch fabric one or more fixation lines comprising coupling means fixating the first layer to the second layer, the one or more fixation lines corresponding to the one or more contours. Furthermore, the drop stitch fabric is coated, wherein one or more coating layers cover at least the one or more fixation lines. The disclosure also relates to an inflatable structure manufactured according to the foregoing, and a control system for controlling said manufacturing.

First claim

The invention claimed is:

1 . A method for manufacturing an inflatable product, the method comprising:
determining one or more contours of the inflatable product to be manufactured; providing a single drop stitch fabric having a first layer and a second layer tethered by drop stitches, the single drop stitch fabric having a layer area greater than an area defined by outer contours of the one or more contours of the inflatable product to be manufactured such that all drop stitch fabric of the inflatable product is continuous and included in the single drop stitch fabric; placing a respective portion of one or more non-inflatable elements between the first layer and the second layer; providing along at least a portion of the single drop stitch fabric one or more fixation lines comprising coupling means fixating the first layer to the second layer and each of the first layer and the second layer to the respective portion of the one or more non-inflatable elements, the one or more fixation lines corresponding to the one or more contours, thereby edges of inner and/or outer perimeters of the inflatable product being formed, a geometry of the inflatable product being thereby defined and fixed by the one or more fixation lines, thus rendering the single drop stitch fabric manageable for further processing; and coating the single drop stitch fabric with one or more coating layers to cover at least the one or more fixation lines fixating the first layer to the second layer and each of the first layer and the second layer to the respective portion of the one or more non-inflatable elements such that the inflatable product becomes airtight and gas proof during use.

2 . The method according to claim 1 , wherein the providing one or more fixation lines comprises providing one or more seams comprising stitches.

3 . The method according to claim 1 , further comprising:
cutting along at least a portion of the one or more fixation lines for removal of residue drop stitch fabric.

4 . The method according to claim 3 ,
wherein the cutting along the one or more fixation lines comprises controlling cutting of the one or more fixation lines by means of a cutting controlling unit comprised in a control system.

5 . The method according to claim 3 , wherein the cutting along the one or more fixation lines comprises cutting along the one or more fixation lines with support from a cutting system and/or machine.

6 . The method according to claim 1 , wherein one or more steps of the method is performed by a control system for controlling the manufacturing,
wherein the determining one or more contours comprises determining one or more contours by means of a contour determining unit comprised in the control system; and/or wherein the providing a single drop stitch fabric comprises controlling drop stitching of a single drop stitch fabric by means of drop stitch controlling unit comprised in the control system; and/or wherein the providing one or more fixation lines comprises controlling provision of one or more fixation lines by means of a coupling controlling unit comprised in the control system; and/or wherein the coating the single drop stitch fabric comprises controlling coating of the single drop stitch fabric by means of a coating controlling unit comprised in the control system.

7 . The method according to claim 1 ,
wherein the providing one or more non-inflatable elements comprises controlling providing of one or more non-inflatable elements by means of an element controlling unit comprised in a control system.

8 . The method according to claim 1 , wherein the providing a single drop stitch fabric comprises providing a single drop stitch fabric with support from a drop stitching system and/or machine.

9 . The method according to claim 1 , wherein the providing one or more fixation lines comprises providing one or more fixation lines with support from a coupling applying system and/or machine.

10 . The method according to claim 1 , wherein coating the single drop stitch fabric comprises coating the coupling means of the one or more fixation lines together with the single drop stitch fabric and at least a portion of the one or more non-inflatable elements.

11 . The method according to claim 1 , wherein the inflatable product is configured as at least one of an inflatable pet cage, an inflatable child restraint, an inflatable kayak, or an inflatable gym mat.
