摘要： An apparatus is disclosed for fabricating a laminate product having a pair of sheet materials spaced by a plurality of flexible parallel vanes which are secured to the sheet material so that planar movement of the sheet materials in opposite directions cause the vanes to shift between open and closed positions. The vane material is formed from a web of material by dyeing the material, drying the dyed material, applying spaced longitudinally extending lines of adhesive on opposite faces of the material, and cutting the material into a plurality of side-by-side strips with each strip having a bead of adhesive on each face and along opposite side edges. The cut material with adhesive applied thereto is taken up on a transfer roll and moved to a vane/strip handling station where the strips of material are processed and delivered to a laminating station in parallel overlapping relationship with each other. The laminating station feeds the sheets of material above and below the strips to form the laminate before passing it through the laminating station where the adhesive is first heat activated to bond the component parts of the covering product together, and subsequently cooled to cure the adhesive. The resultant product is wrapped around a take-up roller for delivery to a remote location where the product can be cut to size and operably connected to a control system to form the final covering product for an architectural opening.

摘要： An apparatus is disclosed for fabricating a laminate product having a pair of sheet materials spaced by a plurality of flexible parallel vanes which are secured to the sheet material so that planar movement of the sheet materials in opposite directions cause the vanes to shift between open and closed positions. The vane material is formed from a web of material by dyeing the material, drying the dyed material, applying spaced longitudinally extending lines of adhesive on opposite faces of the material, and cutting the material into a plurality of side-by-side strips with each strip having a bead of adhesive on each face and along opposite side edges. The cut material with adhesive applied thereto is taken up on a transfer roll and moved to a vane/strip handling station where the strips of material are processed and delivered to a laminating station in parallel overlapping relationship with each other. The laminating station feeds the sheets of material above and below the strips to form the laminate before passing it through the laminating station where the adhesive is first heat activated to bond the component parts of the covering product together, and subsequently cooled to cure the adhesive.

摘要： An apparatus and method for winding a sheet of aligned parallel yarns onto a beam is described. The beam winder utilizes a circularly arced yarn spool rack that feeds each yarn to an alignment comb through associated guide tubes. The distance between each spool of yarn and the alignment comb is substantially the same for all spools of yarn, thereby equalizing the force necessary to pull them to the comb. Next, the aligned sheet of material is preshrunk using heated rollers and wound onto a beam. Multiple speed controlled stepper motors are utilized to maintain a constant low level of tension in the sheet during the shrinking process. After shrinkage, the tension level of the yarn sheet is increased as it is wrapped onto the beam. A turntable that supports two or more beams is provided to facilitate the rapid switching of beams once one beam has become full.

摘要翻译： 描述了将对齐的平行纱线卷绕到梁上的装置和方法。 卷绕机使用圆形的纱线卷轴架，其通过相关联的导管将每根纱线馈送到对准梳。 纱线的每个卷轴和对准梳之间的距离对于所有的纱线卷轴基本上相同，从而使将其拉到梳子所需的力相等。 接下来，对准的材料片材使用加热辊预先挤压并缠绕在梁上。 在收缩过程中，使用多速度控制的步进电机来保持片材中持续的低水平张力。 收缩后，纱线片的张力水平随包裹在梁上而增加。 提供支撑两个或更多个光束的转台，以便一旦一束光束变满，就有助于光束的快速切换。
