卷筒普票是长条的单行邮票盘成卷状出售的邮票版式,这一型式是随着十九世纪末二十世纪初自动售卖机的发明和广泛使用而发展起来的。今天,卷筒普票已在世界范围内广泛使用,除了在自动售卖机中零售以外,通常还以整卷的形式在邮局中出售。由于使用卷筒邮票的主要目的是方便普通邮政用户,因此在各国,卷筒邮票这一形式大都用于普通邮票上,美国也不例外。 The roll of pens is a stamp format sold as a long, one-line stamp plate, which was developed with the invention and widespread use of vending machines in the late nineteenth and early twentieth centuries. Today, roll-pocketing is widely used around the world, except for retail in vending machines, which are often sold in full-scale at the post office. Because the main purpose of using roll stamps is to facilitate ordinary postal users, in many countries the form of roll stamps is mostly used on ordinary stamps, and the United States is no exception.
