Abstract

本发明涉及一种用于连续制造涂层组织体套的方法，该涂层组织体套(1)包括至少一根气密管(2)，并且包括从至少一个涂层组织体面片上切割出的两根条带(15；25)，在这些条带的一个表面上沉积一种粘结材料，折叠条带，将每一折叠条带固定到一第一涂层组织体面片上，在第一面片的表面上及在两条带之间沉积一种防粘剂，将一第二面片压在第一面片上，将两面片连接在一起，再使管(2)膨胀以将两条带展开，在两面片的每一连接区域内在管(2)的内侧，条带形成一成角度的连接。本发明还涉及采用此方法制造的一种涂层组织体套。

Description

连续制造涂层组织体套的方法以及用此方法制造的涂层组织体套
技术领域
[01]本发明涉及一种用于连续制造涂层组织体套的方法以及用此方法制造的一种涂层组织体套。
背景技术
[02]涂层组织体套能被应用于许多场合，比如，用于形成具有气动结构的可充气管，诸如救生筏，或者用于形成梁或可充气结构，或者用于制造比如漂浮的防污染的拦河坝。
[03]这类套包括至少一个管状区域，且由两个组织体面片构成，所述两面片在其一个或两个表面上涂有涂层。此涂层由至少一层橡胶或者由至少一层塑料构成。这种套是通过将这两层涂层组织体重叠并将这两层组织体在至少两个纵向和平行区域内连接在一起而制造的，为了制成至少一根纵向管，所述纵向和平行区域被至少一个非连接区域分开。
[04]然而，以这种方法制造的套存在缺陷，主要在于，在管的内部，两面片(nappe)之间的每一根连接线由一个阻力被减少的区域构成，尤其是当该套经受抗剪应力时，结果其机械性能的等级与所制造的整根管上的性能不一致。
[05]为了制造这种套，另一种方法也是公知的，其包括制造一种编织组织体条带，该条带由多根经线和一根纬线组成并且在其至少一个表面上涂敷一种涂层。
[06]在至少一个纵向区域内，通过使此纬线在下层面片之间交替地穿过并且在上层面片的经线之间交替地穿过，以及通过使此纬线在所述纵向区域的一侧面和另一侧面穿过，而形成一个下层面片和一个上层面片，此纬线在所有经线之间交替，以便形成连接区域并制成所述编织组织体条带，该条带包括至少一个管状区域，所述管状区域以所述连接区域为边界。
[07]然而，在此情形下，管内侧的连接线构成排料段，用于以这样一种方式即它们连续放气而排出管内所包含的空气。

附图说明
[31]根据下面结合附图和实例所作的描述，将能够理解本发明的特征和优点，这些附图中：

[37]图9是示意图，示出采用图8的布局制造的套的一部分。
具体实施方式
[38]图1是示意性透视图，示出一种套的一个实例，该套总体上采用标记1标识。
[39]根据图1所示的实施例，所述套1包括多个管状形式的纵向区域2，而且，在这些纵向区域2的一侧和另一侧，具有一个纵向连接区域3，该纵向连接区域3在每一中心管状区域2的一侧和另一侧封闭。
[40]参见图2至6，将对形成套1的各个元件以及用于制造该套1的方法进行描述，所述套1由一个管状区域2和两个连接区域3组成，每个连接区域3被设置在该管状区域2的一侧和另一侧，所述元件和用于制造套1的方法是类似的，其中，套1由多个平行的管状区域2组成，这些管状区域2被一个连接区域3相互分开，以此类推。
[41]在图2至6中，用以构成套1的各个元件的厚度已经被故意放大，以便于理解。
[42]套1由一个第一面片10组成，该面片10包括一种机织组织体或无纺组织体11，该组织体11由聚酰胺或聚酯纤维或者其它纤维制成。该组织体11由经线11a和纬线11b形成(图7和8)。该机织组织体11在其至少一个表面上覆盖有一层涂层12，在图示的此实施例中，是在机织组织体11的每一个表面上覆盖有一层涂层12。
[43]在组织体11与涂层12之间沉积有一种粘结材料，以便在这两个元件之间形成良好的粘结。这种粘结材料的沉积比如是在一台涂布机上实现的，粘结材料被按配方制造以便在组织体11与涂层12之间形成良好的粘结。
[44]套1还由一个第二面片20组成，该面片20包括一种机织组织体或无纺组织体21，该组织体21也由聚酰胺或聚酯纤维或者其它纤维制成。该机织组织体21由经线21a和纬线21b形成(图7和8)。该组织体21在其至少一个表面上覆盖有一层涂层22。在图示的此实施例中，是在机织组织体21的每一个表面上覆盖有一层涂层22。在组织体21与涂层22之间沉积有一种粘结材料，以便在这些元件之间形成良好的粘结。这种粘结材料的沉积是在一台涂布机上实现的，且粘结材料被按配方制造，以便在组织体21与涂层22之间形成良好的粘结。
[45]沉积在组织体11和21上的涂层12和22由至少一层橡胶或者至少一层塑料构成。涂层12和22沉积在每一组织体11和21上是以传统的方式通过涂覆、通过压延或者通过挤压而实现的。
[46]套1还分别包括两个条带15和25，它们是从未图示的至少另一组织体面片上切割出来的。
[47]条带15包括一种组织体16，该组织体16在其一个表面上覆盖有一个涂层17，该涂层17由一层橡胶或一层塑料形成。组织体16的与包含所述涂层17的表面相对的表面被覆盖有一种粘结材料材料18。以同样的方式，条带25由一种组织体26组成，该组织体26在其一个表面上覆盖有一个涂层，该涂层由至少一层橡胶或塑料形成。组织体26的与包含所述涂层27的表面相对的表面覆盖有一种粘结材料材料28。
[48]条带15和25的组织体16和26还分别由各自的经线16a和26a以及各自的纬线16b和26b形成(图7和8)。
[49]然后，每一条带15和25被折叠，以便将一个折叠到另一个上而分别形成两个半面，所述半面分别涂覆有粘结材料18和28，从而将这些条带15和25保持在折叠状态，如图3所示。已经被以此方式折叠的条带15和25，通过将每一条带15和25的相互面对的半面的分离线15A和25A定位而被沿纵向固定到第一面片10上，以便确定至少一个区域A以用于形成管2，如图4所示。将两个折叠的条带15和25分开的距离是要被制造的管2的直径的函数。
[50]假如在面片10的涂层12与条带15和25的涂层17和27之间的粘结性能足够强，尤其是在涂层是由一层橡胶构成的情形下，通过施加轻微的压力和通过加热每一已折叠的条带，已折叠的条带15和25就被固定到第一面片10上。
[51]然而，假如所述粘结性能不够强，即在所述涂层是由一层塑料形成的情形下，粘结点被附着在每一已折叠的条带15和25与第一面片10之间。
[52]在位于每一条带15和25的所述半面的分离线15a和25a之间的所述区域A内，第一面片10的表面被涂覆有一种防粘剂30。该防粘剂30必须是与沉积在面片10和20上的涂层完全不相容的，在组装两面片10和20的组装温度下，它必须不熔化，如下文所述。该防粘剂是由一种难熔薄膜、一种粉末、诸如，比如，滑石或者膨润土，或者由一种分散体或者一种防粘剂溶液构成。
[53]然后，通过将第二面片20压在设有所述已被折叠条带15和25的第一面片10上，这两张面片10和20就被组装，如图5所示。通过在位于用于形成管2的区域A的一侧和另一侧的连接区域B内进行粘结，将两张面片10和20连接在一起，就是说，在未涂覆防粘剂30的区域内进行粘结。此粘结是通过对两面片10和20施压并同时加热而实现的。
[54]在涂层是由橡胶构成的情形下，加热使它能被硫化，而且在涂层是由塑料构成的情形下，它们能被熔化。压力使得在组织体、面片10和20的涂层以及条带15和25之间提供粘聚力和粘附力。此操作是在一台包括一个或更多辊子的机器上连续执行的，这些辊子被加热并设有千斤顶以便施加压力。
[55]在这些组装操作之后，将气体喷射到位于已被折叠的条带15和25的分离线15a与25a之间的区域A内，其效果是将该区域充气膨胀，从而制成一根管2。在充气期间，条带15和25被展开并且在内部形成该管2，在两面片10和20的每一连接区域内，形成一种成角度的连接，以确保机械性能和密封性，如图6所示。因而，两面片10和20之间的每一连接区域被位于管内部的构成一种成角度连接的一条带加固，这就实现了组装，其能够抵抗剪切，从而在整根管上具有相同的机械性能。
[56]在图7和8中，仅仅示出了面片10和20及条带15和25的组织体11、21、16和26，在这些组织体的经线与纬线之间的间距已经被故意放大，以便于理解。
[57]根据图7所示的第一实施例，面片10的组织体11的经线11a平行于该面片10的纵轴延伸，而其纬线11b垂直于其经线11a延伸。同样，面片20的组织体21的经线21a平行于该面片20的纵轴延伸，而其纬线21b垂直于其经线21a延伸。以同样的方式，条带15和25的组织体16和26的经线16a和26a分别平行于这些条带15和25的纵轴延伸，而它们的纬线16b和26b分别垂直于它们的经线16a和26a延伸。
[58]在此实施例中，用以形成面片10和20以及条带15和25的每一组织体都是由一种被称为直线纤维组织体(straight thread fabric)的组织体形成的。
[59]由于面片10和20以及条带15和25的组织体的经线和纬线的这种布局，形成套1的管2在膨胀之后是直线性的，如图1所示。
[60]根据图8所示的第二实施例，第一面片10的组织体11的经线11a相对于该第一面片10的纵轴倾斜一个角度+α，而第一面片10的组织体11的纬线11b垂直于其经线11a延伸。
[61]然而，当将第二面片20已经压在第一面片10上之后，第二面片20的组织体21的经线21a相对于第二面片20的纵轴倾斜一个角度-α，就是说，在与第一面片10的经线11的倾斜方向相反的方向上延伸，而第二面片20的纬线21b垂直于第二面片20的经线21a延伸。
[62]条带15和25的组织体16和26的经线16a和26a以及纬线16b和26b以与上述第一面片10的组织体11的经线11a和纬线11b相同的方式布局。这样，经线16a和26a就与相应条带15或25的纵轴形成一个角度+α。
[63]当条带15和25已经被折叠之后，下面半个条带的经线16a和26a以及纬线16b和26b就具有与面片10的经线11a和纬线11b相同的布局，而且，上面半个条带的那些经线16a和26a以及那些纬线16b和26b就具有与面片20的经线21a和纬线21b相同的布局。
[64]给定那些经线和那些纬线的方向，套1的管2在充气之后就具有一种圆环(tore)的形状，如图9所示。
[65]以此方式制成的圆环的直径可以根据上述角度α的值进行调整。角度α的取值范围是大于0°至45°。
[66]在这最后一个实施例中，以此方式，用于面片10和20以及用于条带15和25的组织体是由一种被称为斜纹组织体的组织体制成的。
[67]根据本发明的方法被应用于比如膨胀管的制造中，膨胀管可供构造充气结构使用，诸如，比如救生筏、充气快艇、柔性容器或者漂浮的防污染的拦河坝，以及一般地说是采用可膨胀的且是圆柱形展开形状的所有设备。
[68]本方法允许制造一种涂层组织体套，该套包括n个用于形成管的管状区域和n+1个连接区域。如果需要，在连接区域连续实施切割操作可以使管分开。
