摘要： Apparatus for stemming tobacco leaves and for segregating the lighter and heavier parts of the resulting mixture comprises a stemming chamber for a rotary stemming unit serving to stem tobacco leaves which are admitted by way of a first inlet of the stemming chamber. The latter has at least one second inlet for admission of a current of separating air, at least one outlet for evacuation of heavier parts, and at least one outlet for evacuation of lighter parts with the air current. The distribution of outlets is such that the direction in which the lighter parts are evacuated with the air current is at least substantially counter to the direction of evacuation of heavier parts. This can be achieved by using the inlet or inlets for air as outlet or outlets for heavier parts.

摘要： Device for stemming a downwardly flowing stream of tobacco leaves and like materials by beating in a beating zone and separating the lighter portions of the leaves from the heavier portions. In particular, the leaf stems are separated in a main separation zone and at least one secondary separation zone, through both of which an upwardly flowing separation airstream passes. The separation zones are defined by a casing which divides the separation airstream into a main airstream and at least one smaller secondary airstream. The inlet of the secondary zone is located in the main separation zone.

摘要： In a process for obtaining from tobacco leaves fragments of substantially constant shape and more particularly the shape of a quadrilateral having parallel opposite sides, wherein the leaves are subjected to a cutting operation along parallel and equidistant cutting lines, the fragments obtained are subjected to an orientation operation so that the cutting lines should assume a first given direction and the fragments which are thus oriented are caused to undergo a recutting operation along equidistant recutting lines which are parallel to a second given direction, the step of separating from all the oriented fragments which are caused to undergo the recutting operation all those fragments whose projection on a line at right angles to said second direction is smaller in length than the distance between said recutting lines.
摘要翻译：在从烟叶获得基本恒定形状的碎片的方法中，更具体地说，具有平行相对侧面的四边形的形状，其中叶片沿着平行和等距切割线进行切割操作，所获得的碎片经受取向操作使得切割线应该呈现第一给定方向，并且使得如此定向的碎片沿着与第二给定方向平行的等距重新切割线进行重新切割操作，该步骤与所有定向片段分开，使得在与第二方向成直角的直线上的投影的所有片段的长度比所述再切割线之间的距离要长的重新进行操作。
