The adhesive tape having a substrate including 100 parts by mass of a polyvinyl chloride and, with respect to the 100 parts by mass of the polyvinyl chloride, 10-100 parts by mass of an elastomer and 10-100 parts by mass of a plasticizer, wherein the elastomer includes an acrylonitrile monomer unit and at least one monomer unit selected from the group made of a chloroprene monomer unit, a butadiene monomer unit, and an isoprene monomer unit and the adhesive tape has an attenuation value of 2 dB or greater in an acoustic absorption test.

An improved crossbow and improved bow and methods for shooting an arrow from such crossbow and how devices. The improved how comprises a pressure sensitive adhesive (PSA) tape on the rail or arrow rest, the surface the arrow slides over when released. The PSA tape provides a smooth surface for the arrow to glide over thereby reducing friction. This is an improved over prior art products such as rail lube or silicone products. The disclosure also comprises an improved method for shooting an arrow with a crossbow comprising PSA tape on the rail or arrow rest.

A debonding tape includes a first tape layer including a first base layer having a first modulus and a first adhesive layer on the first base layer, wherein the first tape layer has a first diameter. The debonding tape includes a second tape layer on the first tape layer and supporting the first tape layer, wherein the second tape layer includes a second base layer on the first adhesive layer and having a second modulus greater than the first modulus, an intermediate layer on the second base layer, and a second adhesive layer on the intermediate layer. The second tape layer has a second diameter smaller than the first diameter such that a circumferential portion of the first tape layer is exposed in a cross-sectional view.
