Abstract: A fixed clamp and shear member is provided in a combination clamping, sealer and shearing device with a strap guide opening extending through the clamp and shear member adjacent a free end of that member serving as an abutment face which cooperates with a movable clamp for clamping a leading end of strap trained from a strap supply through the strap guide opening and into a loop about an article to be bound. A movable shear member is mounted for sliding movement on the fixed clamp and shear member and is reciprocable between a retracted position, wherein the strap guide opening is exposed for strap feeding and tensioning, and an extended position wherein the movable shear is in lapping relation to the strap guide opening of the fixed shear and clamping member to effect strap shearing. The movable clamp in its operative clamping position serves as a stop for the movable shear and establishes a seal pressing position for the movable shear intermediate its retracted and extended positions wherein the movable shear presses opposed heated strap surfaces into a fused seal after withdrawal of a pivotably supported heating element from between the strap surfaces and before the movable clamp is released to permit final movement of the shear member into its extended position to shear the strap in the strap guide opening from the strap supply.
Abstract translation: 固定的夹具和剪切构件设置在组合的夹紧，密封和剪切装置中，其中带引导开口延伸穿过夹具和剪切构件，邻近该构件的自由端作为邻接面，该邻接面配合可动夹具夹紧 带的前端经由带引导开口从条带供应器训练，并围绕要捆扎的物品进入环路。 安装可移动剪切构件用于在固定夹具和剪切构件上滑动运动，并且可在缩回位置之间往复运动，在缩回位置，其中带引导开口暴露用于带子进给和张紧，以及延伸位置，其中可移动剪切件与 固定剪切和夹紧构件的带引导开口，以实现带剪切。 可动夹具处于其操作夹紧位置，用作可移动剪切件的止动件，并为可移动剪切件在其缩回和伸出位置之间建立密封压紧位置，其中可移动剪切件在可枢转地撤回之后将相对的加热的带表面压入熔融密封件 支撑的加热元件从带表面之间并且在可移动夹具被释放之前允许剪切构件进入其延伸位置的最终移动，以将绑带引导开口中的带从带供应件剪切。
