Abstract

A tape feeding apparatus capable of feeding a tape laminate made by superposing a first tape having a first chemical material layer on one side and a second tape having a second chemical material layer on one side reacting with the first chemical material with the layers in contact with each other. When the chemical reaction occurs between them, the second chemical material layer exhibits an indication which is visually recognized. Rollers press the first tape drawn out from a first reel and the second tape drawn out from a second reel so that the first and second chemical material layers come in mutual contact, and form the tape laminate.
