Description

  The present invention relates to a device for folding a heating element by a folding guide means for folding a folding part of a heating element that is conveyed while being stacked and maintained on the surface of the conveyance means by a folding support means.

The exothermic agent storage portion is divided by a substantially straight intermediate seal portion formed in the substantially center, and each exothermic agent storage portion has a one-side bulging shape that bulges toward the breathable sheet with respect to the non-breathable sheet. The formed body is provided with a release layer on one side of the packaging sheet, and the packaging sheet is mounted so as to be stacked on the adhesive layer formed on the release layer, and the packaging sheet is disposed on the downstream side of the pressing roll.

Normally, a pressure-sensitive adhesive layer is formed on the side of the body that is generally used, and is attached to a non-breathable packaging sheet. That is, a pressure-sensitive adhesive layer with a separator is provided on an outer bag that is a non-breathable storage bag. It was not applicable to the folding of the heating element.
Moreover, since it is an essential condition that the warmer is fixed to the pressure-sensitive adhesive layer provided on the outer bag, it cannot be applied to a heating element that is not fixed to the outer bag via the pressure-sensitive adhesive layer.
In addition, a heating element having three or more divided heating portions other than the case where a pressure-sensitive adhesive layer as a warmer fixing layer when using a warmer is provided on an outer bag and the warmer is fixed to the pressure-sensitive adhesive layer In this case, it was bent between the divided heat generating portions, and the rise of the valley fold shape did not start well along the intermediate seal portion of the body of the warmer by the pressing roll, resulting in a failure in folding.
In addition, there is a problem that the folding finish is unstable and defective products are likely to occur.

No. with eight lines written at 45 degree intervals radially from the center point. 2 (JIS P 3801 type 2) filter paper is placed on a stainless steel plate, and a template of length 150 mm × width 100 mm having a hollow cylindrical hole with an inner diameter of 20 mm × height of 8 mm is placed at the center of the filter paper, Place the sample near the hollow cylindrical hole, move the push plate along the mold plate, put the sample into the hollow cylindrical hole while pushing the sample, and scrape the sample along the mold plate surface (mold push molding) ).
Next, in order to prevent an exothermic reaction during the measurement, a non-water-absorbing 70 μm polyethylene film is placed so as to cover the hole, and further, a thickness of 5 mm × length of 150 mm × width of 150 mm is placed thereon. Place a stainless steel plate and hold for 5 minutes. Thereafter, the filter paper is taken out, and the trace of water or aqueous solution soaking is read in millimeters as the distance from the circumference that is the edge of the hole of the hollow cylinder to the tip of the soaking, along the radial line. Similarly, the distance is read from each line to obtain a total of eight values. Each of the eight values read (a, b, c, d, e, f, g, h) is taken as a measured moisture value. The arithmetic average of the eight measured moisture values is taken as the moisture value (mm) of the sample.

Five points are measured for the same sample, the five ready water values are averaged, and the average value is taken as the ready water value of the sample. In addition, when measuring the mobile water value of the exothermic composition in the heating element, the moisture content for measuring the true moisture value is calculated by calculating the moisture content of the exothermic composition from the moisture content measurement using an infrared moisture meter of the exothermic composition. Based on this, the amount of water necessary for the measurement is calculated, and the true water value is measured and calculated from the amount of water.
