Application: On the Shaft, and Off It

The adhesive does two jobs at once: it lets air out while the film goes on, and lets go again when heat is applied.

The adhesive is the part of a wrap nobody sees and the part that decides everything: it holds the film to the tube for a season, it lets the air out from under the film while it is being laid, and it gives the film up again when it is warmed. Two of those three jobs happen on the day the wrap goes on, and the third happens the day it comes off.

The tube before the film

A pressure sensitive adhesive bonds to a surface, not to whatever is lying on a surface, and a shaft out of a quiver is carrying skin oil, silicone from a polishing cloth or dust in a film thin enough to be invisible. Any of them becomes the layer the adhesive holds to, and the bond is then only as good as the layer. The air release layer makes the demand stricter, because its channels are finer than a particle of dust, and a channel that is blocked stops working in that place.

Preparation is short and it is ordered. Isopropyl alcohol on a lint free cloth, one pass in one direction, a fresh area of cloth for each shaft, and a wait long enough for the surface to be dry to a fingertip. Surface preparation carries the checklist and the reasons behind it, including why a circular wipe puts back what it lifted and why a cold tube takes a film badly.

Pressure, and the road out for the air

The film is laid from the seam edge along the tube, not around it, and pressed from the seam outward, so the air under it is pushed toward the channel pattern rather than trapped ahead of the pressing thumb. Where the air has a road out, no bubble forms; where it does not, no amount of pressure moves the bubble afterwards. The trick of the product is that the road is built into the adhesive face and not into the way it is applied, which is what lets a band of film go on without a squeegee.

What the film crosses on its way round the tube is the other half of the operation, and it is a geometry question: cut lines and overlap reads where the seam lands and what the doubled film does to the print.

Heat, and the way back

A pressure sensitive adhesive is a solid that flows, and warmth makes it flow readily. Warm the film, lift an edge at the seam, and pull the film back on itself at a low angle with the heat just ahead of the peel front: the band comes off in one piece and the tube is the tube that was prepared before the film went on. Removing a wrap with heat describes the temperature, the direction of the pull, and what the residue says about how the film was put on.

Removal has a cost the register counts rather than hides. A wrap that sits under the fletching takes the vanes with it when it goes, so refletching is part of the price of the film, and a wrap removed is a few grains taken off the tail of the arrow.

Why application is a docket

The film's behavior on the tube is a property of the film, and the register reads it as one. Whether it holds depends on the preparation and the adhesive; whether it comes off cleanly depends on the same two; and what it adds to the arrow while it is on depends on the gauge, which the balance docket reads and the spec table records with its inputs and its dates. The words of the bench, including air release and pressure sensitive, are given in the glossary.

      Heat and the Second Half of the Adhesive Job

      The adhesive that lets air out while the wrap goes on also lets go when it is warmed. Removal is the same film read backwards.
