最后再分割复合竹型材 25为多个片状的竹材饰片 26，且其分割面均平行 于复合竹型材平面 251，而形成表面具格状紋的竹材饰片 26， 方格 261内并有 原生竹纹 262。
另外请参照图 4所示为本发明的分割复合竹型材侧面为多个竹薄片或竹 平板的示意图， 上述分割复合竹型材 25除了可平行复合竹型材平面 251分割 之外， 还可令其分割面均平行于复合竹型材侧面 252， 使其成为多个片状的表 面具斜状紋 263的竹材饰片 26a。
上述制造过程中， 因不包含对各步骤中的竹材实施高含水率处理， 干燥 处理其竹材绝干含水率小于 20%， 即俗称的干式法。 故在上述干式法的分割复 合竹型材 25的制造过程可运用锯切机 (Saw Machine)设备的刀具 253， 锯切成 竹平板的具格状纹或斜状纹的竹材饰片 26，其竹平板的厚度为 1. 5mm至 5. 0mm 间。
且， 运用上述干式法时， 其胶合步骤中所用的胶合剂为具耐水性的尿素 胶 (urea adhesive)、美腊明胶 (Melamine adhesive)、酷胶 (phenol adhesive)、 醋酸乙稀胶合剂（Polyvinyl Acetate adhesive)、 雷索辛胶（Resorcinol resin adhesive)等或上述胶合剂的改质胶。
另外， 在前述制造过程中， 也可在取得筒状原竹竹材 20时、 形成竹片竹 材 21时、 形成条状方形断面的竹型材 22时或形成板状单元 23的任一个或多 个步骤后， 还包含一保持原生竹髙含水率或实施高含水率处理步骤穿插其间， 此即所谓湿式法。此一湿式法是在包含下列各制程步骤中：如对筒状原竹竹材 20、 对竹片竹材 21、 对竹型材 22或对板状单元 23时， 保持原生竹高含水率 或将其置于蒸气室或煮沸槽或浸泡水中，作高含水率处理，俾于竹纤维吸收水 份， 增加绝干含水率达 25%以上， 使竹纤维软化， 降低竹材内应力， 以利平切 机 (slicer)等设备的刀具 253切削为厚度达 0. Iran至 2. 0mm间的竹薄片厚度的 竹材饰片 26。
且， 运用上述湿式法时， 其胶合步骤中所用的胶合剂为聚氨酯树脂胶合 剂（polyurethane adhesive)或耐水性的醋酸乙稀胶合剂（Polyvinyl Acetate adhesive)等。
又， 运用上述干式法或湿式法而形成表面具方格 261格状纹的竹材饰片 26， 其方格 261的宽度紋为形成竹片竹材 21时的宽度边缘， 方格 261长度纹 由侧向斜切 (非必须裁切于对角在线)复合竹型材的斜切面 241 与复合竹型材 25原底面所夹角度 a来形成 (如图 2A所示）， 其较佳角度为 5° 至 70° 之间， 其角度 α愈大则方格长度愈短， 反之角度 a愈小则方格长度愈长。
上述的干式法或湿式法制造过程中， 在最后分割复合竹型材 25为多个片 状的竹材饰片 26步骤之后， 还可包含接合片状竹材饰片 26、 26a以形成更大 面积、 统一斜向或交错斜向等紋路的竹材饰片 (请参照图 5A、 图 5B、 图 5C及 图 5D所示）。
另， 利用上述的本发明所制成的竹材饰片 26、 26a制品， 具有独特的、 制成过程中所形成的格状紋或斜状纹 263， 可供贴合在绵纸、 不织布、 夹板、 硅酸钙、 塑料板、 金属板等各种基材作表面装饰用， 以提高产品的附加价值。
综上所述， 为本发明为解决问题所采用的技术手段的最佳实施方式或实 施例而已， 并非用来限定本发明专利的范围。 即凡属于本发明专利申请范围， 或依本发明专利范围所做的等效的变化与修改， 皆为本发明专利范围所涵盖。 工业应用性 本发明利用现有技术的单调的直条接合饰纹演化为格状纹或斜状纹，并可 进一步控制其格状紋的方格大小或斜状纹的斜纹角度，使其竹材饰片产生更多 样的紋路变化， 以更能满足客户多样化的需求。
