#CMT# #/CMT# The paper clip (1) is made of a connected piece wire, which is twisted at an angle (w) with its parts around a paper clip surface (5). The angle of twist of the wire is approximately 330 degree to 480 degree. One of the end parts (2) of the wire goes through the paper clip surface framed at the other end part (3) and the middle part (4) of the wire and intersects a section (6) of the middle part of the wire limiting the other end part. The front sides (8,9) of the wire are placed at opposite ends (10,11) of the paper clip. #CMT#USE : #/CMT# Paper clip for detachable connection of several sheets with each other. #CMT#ADVANTAGE : #/CMT# The paper clip is made of a connected piece wire, which is twisted at an angle with its parts around a paper clip surface, and hence ensures a safe and simple structure of the paper clip. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of paper clips. 1 : Paper clip 2,3 : End parts 4 : Middle part 5 : Paper clip surface 6 : Section 8,9 : Front sides 10,11 : Opposite ends w : Angle. |
