    • The invention relates to a method for producing pressure-sensitive adhesives that have low or no anisotropy, the process elements including an adhesive supply system, an application unit and a placement element. A melt strip of the pressure-sensitive adhesive is produced between the outlet of the application unit and the point of placement on the placement element and is stretched. The invention is characterized by controlling the stretching of the pressure-sensitive adhesive in the free melt strip by adjusting an effective ration G which is defined as the ratio of the effective time Δt of the stretching to the stretching rate R, and which is adjust to a value of not more that 0.008 s2. The effective time Δt is defined by the formula 2 Lr/[vstrip (1+r)] wherein L is the length of the melt strip, r is the stretching ratio and vstrip is the speed of the melt strip and the stretching rate R is defined as a temporal derivative of the stretching ratio r.
    • 本发明涉及一种具有低或无各向异性的压敏粘合剂的制造方法,所述工艺元件包括粘合剂供应系统,涂布单元和放置元件。 在施加单元的出口和放置元件上的位置之间产生压敏粘合剂的熔融条,并且被拉伸。 本发明的特征在于通过调节定义为拉伸的有效时间Deltat与拉伸速度R的比值的有效比例G来控制自由熔融条中的压敏粘合剂的拉伸,并将其调整为 不大于0.008s <2的值。 有效时间Deltat由公式2 Lr / [v> strip(1 + r)]定义,其中L是熔体条的长度,r是拉伸比,v带 / SUB>是熔条的速度,拉伸速度R被定义为拉伸比r的时间导数。

    • Process for producing a pressure-sensitive double-sided adhesive tape, in which a) a ready-made rubber-based backing material is introduced into a screw extruder, where 1. the backing material is heated by means of heating elements present on the screw extruder, 2. in a degassing zone, the backing material is freed from volatile constituents by means of the application of reduced pressure, 3. the backing material is homogenized and brought to the intended temperature, b) in a co-extrusion adapter, a barrier layer conveyed by means of a further appropriate melting and conveying unit is placed onto the backing material on both sides, c) the resulting intermediate laminate is supplied to a three-channel slot die and is uniformly extruded in web form, d) in the said three-channel slot die a pressure-sensitive hotmelt adhesive, supplied in each case with the aid of an appropriate melting and conveying unit, is applied, top and bottom, over the whole area of the intermediate laminate, e) the adhesive tape thus produced is placed onto an antiadhesive substrate, preferably siliconized paper, f) if desired, the adhesive tape is cooled and crosslinked.
