Inflatable Repairs Re-stitch Seams
Re-Stitching of seams on any section of a small bounce house or giant super slide require expert knowledge.
Initially, the rule of thumb in re-stitching seams on a bouncer requires the sewing technician to re-stitch behind and as close as possible to the original manufactured seam line for a couple of reasons:
(1) Jumpers require continuous air flow for proper inflation. Consequently, when a needle perforates the vinyl during manufacturing, a tiny hole created by the puncturing of the vinyl by the sewing machine needle is filled by the thread used to stitch together two pieces of vinyl. Thus air flow loss is restricted by the thread sealing the hole. However, when the thread fails and the two pieces of vinyl require re-stitching, and the vinyl is stitched by creating another continuous sewing line, you now have a seam of needle holes that are not sealed by thread. Therefore, the bounce house has a line of punctured holes from original manufacturing where air loss is prevalent. This is precisely the reason for sewing the vinyl together with a stitch line behind the original manufactured stitch line. The original manufacturing stitch line with exposed air holes is now on the outside of the new stitch line, and is sealed by the new stitch line barrier.
Now you must be asking yourself how much air loss would occur from such small needle holes? Well, in theory, your thinking may seem right. However, take into account that your inflatable has aged and consequently all original manufacturing stitches have stretched due to the constant stress of jumping. Now what you have is thousands of sewing needle holes throughout the Spacewalk or Moonwalk inflatable that are releasing more air than when originally manufactured. Compound that by adding more non thread-filled needle holes and, bingo, your jumper is now beginning to require substantially more air intake to maintain proper and firm inflation. At this point, unless you repair a failed seam properly, your inflatable jumper will begin to show signs of middle-age or, even worse, find its way to premature retirement.
(2) There are numerous so-called inflatable repair shops (shade-tree ‘sewing’ mechanics) as we refer to them, that will attempt to re-stitch a failed seam along the same original manufacturer’s stitch line. This will not hold-up over the long-haul because when you stitch over an existing stitch line, you are stitching unto an area of the vinyl that has been compromised and severely weakened by previous substantial stress to the original stitching. THIS TYPE OF REPAIR WILL UNTIMATELY FAIL AGAIN … sooner rather than later. You’ll undoubtedly have your inflatable in the shop for the more repairs in the same area again!
