First, a sample holder is lowered such that a sample is held. Next, a roller or a plate-shaped member is lowered and pressed to an adhesive surface A of a sample At this time, a tape is disposed between the roller or the plate-shaped member and the adhesive surface A of the sample and a fixed pressure load is applied to the sample Then after a fixed period of time has passed, the tape 23 is pulled from the sample by the raising of the roller or the plate-shaped member and an adhesive strength is measured with a load cell according to the tension of the tape at that time. After measuring, a take-up reel is rotated so as to wind up a predetermined pitch of the tape and an unused portion of the tape is reeled out to the tip of the roller or the plate-shaped member

Device and method for measuring adhesive strength

By linking together a first set of identification information and a second set of identification information, and by creating a database linking together manufacturing information, sales information, and distribution information with the first identification information as a keyword, the burden on the user of controlling manufacturing can be lightened by, for example, the manufacturing information side informing the sales information side that the product renewal date is approaching. Further, a response can rapidly be made to demands from the user, and steps rapidly taken (i.e. transmitted to the manufacturing process and put into practice) to meet those demands.

Rubber product control method using identification marking

An information indicator used for a tire production control label or the like is provided with a film-type substrate formed of a heat-resistant resin. An information indicating surface onto which a recognizable indication indicating specified information is printed is formed on one surface of the substrate, and a pressure sensitive adhesive layer is formed via a primer layer on the other surface of the substrate. The information indicating surface is formed so as to have a surface roughness whose arithmetical mean deviation of the profile determined in JIS B 0801 lies between 0.5 and 5 .mu.m, and an indication such as a bar code, characters, figures, symbols or drawings is attached to the information indicating surface. With the information indicator formed in this way, the indication does not become blurred or erased even under the high temperatures and high pressures during vulcanization.
