Abstract: The invention relates to a letter opener having a transfer member which transfers the envelope to be opened at an angle (a) to the cutting line and takes the form of a belt (8). The oblique position of the belt (8) ensures that while the envelope is being cut open, it is always pressed against the blade and, consequently, cut along the whole edge. A circular blade (1) which has a counter-roller (2) and only cuts the envelope open on one side can be provided as a cutting member.

Abstract translation: 开信刀，一个信封以一角度（a）一对切割线朝向皮带（8）的形式传输所传输构件被打开。 由带的这个倾斜位置（8）确保了在切割时的包络线朝向刀，并因此沿整个边缘被切割总是按压。 作为在具有反辊（2）一侧仅包络aufschneidendes圆形刀（1）的切割元件可被提供。

Abstract: The invention relates to a mechanical letter-opener. This letter-opener comprises a support (S), a cutting blade (10) which is substantially straight and attached to the support, a means (P1 to P7) for the blade to pivot freely around at least one rotational axis (R1) in relation to the support, a guide member (11a) for moving the envelope in an area and in one direction of movement, and resilient return means (16) for returning the blade to a starting position once it has been rotated by the driving action of the envelope in relation to the support. This letter-opener is characterized in that the pivot means (P1 to P7) provides at least one second rotational axis (R2), distinct from the first, for the blade. This letter-opener is intented for the opening of envelopes of all kinds, whether manually or automatically.

Abstract: A letter-opener comprises a grip element (1) which terminates in two branches (11). The branches (11) enclose a slot (2) into which the free end of the opening element (3) extends. The branches (11) form grips for the user's hand. The gripping points are thus immediately adjacent to the point of application of the load on the opening element (3).

Abstract: An implement is provided for opening envelopes in which a ram (28) is reciprocally mounted within a hollow sleeve (14). A transverse envelope receiving crevice or slot (22) is defined at one end of the sleeve (14) and the ram (28) carries a blade (32) which has a cutting edge (34) directed toward the envelope receiving slot. A spring (38) acts between the sleeve and the ram to urge the cutting edge of the blade away from the transverse slot so that the blade is not exposed unless the spring bias is overcome. Alternatively, a blade (120) is disposed within a body (114). A guide within the body (114) limits movement of the blade (120) to a linear path between a position wherein the cutting edge projects into the crevice (118) in the direction of the width thereof and a position wherein the cutting edge is withdrawn from the crevice (118). A dial (184) is eccentrically mounted on the body (114) in the path of movement of a slide (124) and is rotatable to adjustably limit the extend of projection of the cutting edge (122) of the blade (120) into the crevice (18). The dial prevents the blade from spanning the crevice entirely.

Abstract: The object of the invention is to enable a sealed, conventional envelope to be opened without the use of instruments. This is achieved by securing a strip (10 and 11) on one of the internal surfaces of the envelope, one longitudinal edge of the strip abutting a longitudinal edge (9) of the envelope and having an end (11) protruding outside the envelope.
