New & revolutionary solution for solving an old shoe making problem: Tacking insoles without using nails – TapePeel


TapePeel Shoemachinery GmbH is a brand new company with a brand new product aimed at solving an age old shoemaking problem.

The mechanical industry of the sector has been committed for years to finding an alternative to tacks or nails traditionally

used to attach the insole to the last before mounting to the upper. The results have never been very satisfactory,

until the system “Tape Peel” was introduced to the market.

Designed and manufactured by Andreas Kern “TapePeel” has undergone a Major evolution in just a few years;

an evolution that made it suitable to be adopted by the most renowned companies, such as Hermes, Gucci, and Chanel. And other more!

“Tape Peel” is now available in two versions that differ in the strength of the gluing element:

“Strong” and “Very strong”.

The “Strong” version holds the insole with an adhesive strength of about 1.5 Kg, while

the “Very strong” version has an adhesive strength of about 2.5 Kg (with another type of adhesive).

 The latter is suitable for both “Ago” and “Goodyear” processing. The “Tape Peel” gluing element

has a particular structure - the gluing surface sticking to the insole is reduced to two Points.

This allows preserving the surface of the insole, regardless the material it is made of.

Furthermore, special foam increses the thickness of the glued element, enabling to combine insole and outsole in a perfect way,

also when the surface is not even.

The structure of each element is realised so as to prevent any  forward or backward displacement during the assembly process. 

Moreover the machine for the automatic application of 'TapePeel' has been developed with a new Transfer block that

guarantees a better application for each single gluing element. - Please check the videos !



However, even more serious are the possible consequences for the purchaser of the finished shoes: there is the danger that a small broken staple or nail can remain undiscovered in the shoe. This is why the use of nails in the production of shoes has been forbidden in many countries. It can also occur that when gluing the soles of the shoes, glue runs into the perforation of the insole and can cause pain when wearing the shoes. This feeling can also happen if the perforation is caused by the nails or staples and a pinhole was created on the insole.


There was no practical alternative until the advent of advanced adhesive products such as hot melt and double-sided tapes in the second half of the last century. Various ideas have been tried since then and, while they did work, there were still drawbacks. Hot melt could damage the surface of the insole and was difficult to remove from the last bottom. The pressure sensitive adhesive used on double-sided tapes could ‘build’ in bond strength during the shoemaking process and tear when the last was removed, again leaving residue on both last and insole. Nevertheless, a number of countries banned the use of tacks and staples, so manufacturers had to make the best of what was available. TapePeel may now have found a way round these problems.


A clever idea


TapePeel can be removed in less than a second.The system is again a form of double-sided tape but, this time, with a major difference. The tape remains folded and flat on the lasts and thus the insole can be positioned on the lasts without changing the production procedure. When the correct position has been reached the insole will be fixed on the last.  After fixing, the tape cannot be completely removed as there is a certain amount of tension between the insole and the lasts. To ensure a perfect result one has to use two ore more gluing elements for each last.  There is claimed to be no damage to the surface of the insole and no residue left on the last. The adhesive used has been specially formulated for the purpose and is patent pending.


TapePeel in fact has adhesive on one side only but is folded. It also has only two small areas of adhesive on the side in contact with the insole compared to a single large area on the one in contact with the last . This makes it easier to peel from the insole than from the last and ensures it is left on the latter rather than in the shoe.


It also results in much less damage to the surface of the insole than is the case with hotmelt or conventional double-sided products.


Tests have shown that the adhesive tape can be peeled off from certain kinds of leather completely residue-free and without any other traces remaining. This allows the insole to be coated with the sock prior to being tacked. As a result, the ensuing complicated inclusion of the final sock sole does not occur. As mentioned, the tape always remains on the last and can be easily and quickly peeled off after the delasting process.


The application machine is controlled by an electronic eye which ensures that the tape applied in the right place and that the fold faces the toe of the last. It then remains folded and flat on the last bottom while the insole is correctly positioned after which it will be held flat to the last bottom.


In the course of production the placing of the elements does not have to be to the nearest millimeter or exactly square, so that this process step can, without any problems being incurred, be done by unskilled workers. The time needed for this process is the same as when using nails and clips but the handling of the last and insole is much more convinient.

When using metal bottom lasts one does not have to observe the cut-outs in the metal as would be the case when using staples and nails, but can simply glue the insoles.


For the best results, two or more pieces of tape should be used as this will hold the insole straight on the last. The adhesive system used is compatible with all types of lasts both with and without metal bottom plates. Each roll of tape contains 2,000 pieces.


This is a well thought out solution to an old problem.


The key part is the dual peeling action; first from the insole and then from the last. This is made possible by the use of two areas of adhesion of unequal size


It will mean that there is one more problem shoe manufacturers will not have to worry about.


From the earliest days of shoemaking, insoles have been attached to the last bottom prior to lasting with tacks or nails. It was fast, cheap and convenient; it also had downsides, as they had to be removed before the sole was attached. This left small holes in the insole that were visible inside the shoe and damaged last bottoms. The disadvantages that exist when using staples and nails in shoes production are well known. The nails and staples tend to destroy the lasts when being pulled out after tacking, and the staples and nails are sometimes also found in the machines and can result in the machines breaking down completely.
