摘要： Apparatus for inserting sheets of paper into an envelope. The apparatus includes: a first bursting module for separating a first web of paper into discrete sheets; a conveying device for conveying the discrete sheets from an upstream location to a downstream location along a feed path; a device for feeding a second web of paper having a plurality of longitudinally spaced lines of weakening oriented perpendicular to the feed path; a device for turning the second web of paper parallel to the feed path; a bursting device for bursting the second web into discrete sheets; a device for conveying the second web discrete sheets to the first web discrete sheets; a device for conveying the first web and the second web discrete sheets downstream along the feed path; and a device for inserting the first web and second web discrete sheets into an envelope.

摘要： Apparatus for transporting a web of paper having tractor holes along only one margin thereof. The apparatus includes: a tractor drive having a first pair of pulleys and a first belt mounted on the first pair of pulleys, the first belt having a plurality of sprockets for engaging the paper tractor holes; and an auxiliary vacuum drive system for engaging the marginal portion of the web of paper without tractor holes, the auxiliary drive system having (a) a second pair of pulleys and a second belt mounted on the second pair of pulleys, the second belt having a plurality of apertures at equally spaced intervals extending longitudinally of the length of the second belt, the second belt having an upper and lower reach, (b) a device for applying a vacuum to the apertures in the upper reach of the second belt, (c) a device for varying the amount of vacuum applied and (d) a device for driving the upper reach of the second belt at about the same linear velocity as the linear velocity of the tractor drive sprockets, whereby the vacuum can be turned off during constant velocity or deceleration motions of the web, thereby dissipating tolerance build-up between the tractor drive and the auxiliary vacuum drive system.

摘要翻译： 用于沿着其一个边缘运送具有拖拉机孔的纸幅的设备。 该装置包括：具有第一对滑轮的拖拉机驱动装置和安装在第一对皮带轮上的第一皮带，所述第一皮带具有用于接合纸拖拉机孔的多个链轮; 以及辅助真空驱动系统，用于在没有拖拉机孔的情况下接合纸幅的边缘部分，辅助驱动系统具有（a）第二对滑轮和安装在第二对滑轮上的第二皮带，第二皮带具有 （b）用于向第二皮带上端的孔施加真空的装置（c），其特征在于，所述第二皮带具有上下距离， ）用于改变施加的真空量的装置和（d）用于以与拖拉机驱动链轮的线速度大致相同的线速度驱动第二带的上部装置的装置，由此可以在常数期间关闭真空 纸幅的速度或减速运动，从而消除拖拉机驱动器和辅助真空驱动系统之间的公差积累。
