る。Prior art and problems For example, as an adhesive for electronic parts,
As shown in the figure, a base material 4 in which a double-sided adhesive sheet 42 is laminated on a releasable sheet 41 is passed through a cutting process using a Thomson blade 5, and the double-sided adhesive sheet 42 is laminated on a peelable sheet 41.
2, make a cut that matches the shape of the parts to be adhered, and then remove unnecessary portions 421 of the double-sided adhesive sheet and place a regular-shaped double-sided adhesive piece 4 on the releasable sheet.
20, .
この接着材の使用要領は、第５図に示すように
接着材Ａを連続的に一定速度で引出し、間欠的に
送られてくる被接着部品７に両面粘着片４２０を
転写することにある。 The procedure for using this adhesive is to draw out the adhesive A continuously at a constant speed as shown in FIG. 5, and to transfer the double-sided adhesive piece 420 onto the parts 7 to be bonded that are intermittently fed.
この場合、両面粘着片間の間隔には、厳密な寸
法精度が要求され、その間隔に“狂い”があれ
ば、両面粘着片の転写貼付状態にずれが生じる。 In this case, strict dimensional accuracy is required for the spacing between the double-sided adhesive strips, and if there is any "misalignment" in the spacing, deviations will occur in the transferred and pasted state of the double-sided adhesive strips.

に対する寸法安定性のために有利であると考えら
れる。 By the way, as the above-mentioned releasable sheet, a polyethylene film is considered to be more advantageous than a releasable sheet based on paper material because of the good releasability of polyethylene and the dimensional stability against moisture.
しかしながら、ポリエチレンフイルムは引張り

乾燥の影響で寸法が変化し、常に目的とする間隔
のものが得られないという欠点がある。 However, polyethylene film has a small tensile Young's modulus, and during the process of cutting the double-sided adhesive sheet with the above-mentioned Thomson blade, the releasable sheet stretches, and the spacing between the regular adhesive pieces tends to become "misaligned." In addition, releasable sheets based on paper material have little elongation during the cutting process, but they absorb moisture and
The disadvantage is that the dimensions change due to drying, and it is not always possible to obtain the desired spacing.
考案の目的
本考案の目的は、定形両面粘着片間の間隔を切
断工程を経た後及び経日後においても充分に一定
となり得、かつポリエチレンの秀れた良剥離性を
利用せる剥離性シート材を提供することにある。Purpose of the invention The purpose of the invention is to create a releasable sheet material that can maintain a sufficiently constant interval between regular double-sided adhesive pieces even after the cutting process and over time, and that utilizes the excellent releasability of polyethylene. It is about providing.
