    • A method and apparatus (20) for forming coreless rolls (15) of pressure sensitive adhesive tape involves the use of a mandrel assembly (55) having a specific circumferential tape supporting segment (234) thereon for winding tape. The circumferential tape supporting segment (234) has a tape engaging surface portion (246) that, in a radial orientation, is compressible yet sufficiently stiff to support the tape as it is successively wound about the mandrel (55) to form a tape roll (15), and that is sufficiently pliant to permit ready axial removal of a wound tape roll (15) from the mandrel (55). The innermost wrap (72) of pressure sensitive adhesive tape about the mandrel (55) is masked by an adhesive liner (73). That liner (73) is formed from one portion of a liner/tab strip (123) which had been applied to the tape previously, and prior to winding, the tape is severed, and the remainder of that liner/tab (76) forms an end tab on the outermost end (75) of the previously formed coreless tape roll (15). The liner/tab strip (123) is applied by advancing the liner/tab material (90) laterally across the advancing web of pressure sensitive tape (26) adjacent a first, adhesive bearing side (27) thereof, cutting the liner/tab material (90) to a length approximating the width of the web (26), urging the leading lateral edge portion (190) of the cut liner/tab strip (123) against the first, adhesive bearing side (27) of the advancing web (26) and urging the remainder of the liner/tab strip (123) against the advancing web (26) as the web (26) carries the liner/tab strip (123) away.
    • 用于形成压敏胶带的无芯辊(15)的方法和设备(20)包括使用其上具有特定圆周带支撑段(234)的心轴组件(55)用于卷绕带。 周向带支撑段(234)具有带接合表面部分(246),该带接合表面部分(246)在径向方向上是可压缩的但足够坚硬的,以便当其沿着心轴(55)连续地缠绕以形成带卷 15),并且其足够柔顺以允许从心轴(55)轴向移除卷绕带卷(15)。 围绕心轴(55)的压敏粘合带的最内层(72)被粘合衬垫(73)掩蔽。 该衬套(73)由先前已经施加到带子上的衬垫/接片条(123)的一部分形成,并且在卷绕之前,带被切断,并且该衬里/突片(76)的其余部分形成 在先前形成的无芯胶带卷(15)的最外端(75)上的端部突片。 通过使衬套/凸片材料(90)横向穿过邻近其第一粘合剂承载侧(27)的压敏胶带(26)的前进幅材,使衬垫/突片材料(90)前进 (90)延伸到接近幅材(26)的宽度的长度,将切割衬里/接片条(123)的前侧边缘部分(190)压靠在推进幅材的第一粘合剂承载侧(27)上 26)并且当腹板(26)承载衬垫/突片条(123)离开时,衬垫/突片条123的其余部分抵靠前进卷筒纸(26)推动。

    • A web winding system for winding adhesive backed web on cores mounted on wind-up spindles. The web is supported on a rotating suction drum. A knife mounted on a rotating wheel cuts the web against the supporting drum. A tab bar is mounted on the wheel adjacent to the knife, and applies a tab to the web in registration with the cut. In a second position of the wheel a tab source moves toward the tab bar and applies a tab to its surface. The knife is heated by a heater to a temperature above adhesive softening and below adhesive carbonizing to prevent adhesive to stick to or to accumulate on the knife. The web is lead to the supporting drum around a stationary gapping roller and a retractable gapping roller, mounted on an arm which is pivotable around the roller. When the knife has cut the web the arm pivots clockwise, and lengthens the distance between retractable roller and supporting drum, thus forcing the web to slide on the drum, and to form a gap between the leading cut end and the trailing cut end of the web. The gap allows for flying transfer of the web between the cores on the two wind-up spindles.
    • 卷绕卷绕系统,用于将安装在卷绕轴上的芯上的粘合剂背衬卷绕。 卷筒纸支撑在旋转的吸盘上。 安装在旋转轮上的刀将纸幅相对于支撑滚筒切割。 标签杆安装在与刀相邻的轮上,并且将标签施加到与切割对准的幅材上。 在轮的第二位置,突片源朝向突片杆移动并在其表面上施加翼片。 刀被加热器加热到高于粘合剂软化的温度,并且低于粘合剂碳化,以防止粘合剂粘附或积聚在刀上。 腹板通过固定的间隙滚筒和可伸缩的间隙滚轮导向支撑滚筒,该滚轮安装在可围绕滚筒转动的臂上。 当刀已经切割腹板时,臂顺时针枢转,并且延长可伸缩辊和支撑鼓之间的距离,从而迫使腹板在滚筒上滑动,并且在前切割端和后切割端之间形成间隙 网页。 间隙允许在两个卷绕轴之间的芯之间飞行传送纸幅。
