摘要： An apparatus for forming aligned front and rear hand holes in the front and rear panels of a bag according to the invention has a support having a front face and an oppositely directed rear face adapted to respectively support the front and rear panels of the bag and formed with respective aligned front and rear annular recesses of a shape corresponding to that of the hand holes to be cut. Respective annular front and rear outer holddowns are engageable with the respective faces for pressing the respective panels thereagainst around the respective recesses. An annularly continuous front cutter blade is engageable in the front recess and an annular but discontinuous rear cutter blade is engageable in the rear recess. A rear inner holddown is also engageable with the rear face within the recess. An actuator can press the holddowns against the respective faces and simultaneously press the blades into the respective recesses and thereby cut a piece from the front panel and form an annular but discontinuous cut in the rear panel.

摘要翻译： 根据本发明的用于在袋的前后面板中形成对准的前后手孔的装置具有支撑件，其具有前表面和相对方向的后表面，该后表面适于分别支撑袋的前后面板并形成 其各自对准的前后环形凹部具有与要切割的手孔相对应的形状。 相应的环形前后外压板可与相应的表面接合，以在相应的凹槽周围挤压相应的面板。 环形连续的前切割刀片可接合在前凹部中，并且环形但不连续的后切割刀片可接合在后凹部中。 后内侧按压也可与凹部内的后表面接合。 致动器可以将压紧按压在相应的表面上，同时将刀片压入相应的凹槽中，从而从前面板切割一片，并在后面板上形成环形但不连续的切口。
