Title: Device for stopping sheet
Inventor: MAETANI MASAMI
IPC: B65H26/00
Filed: 1982-12-14
Abstract: PURPOSE:To shorten the time of search and promote the accuracy of the search, by providing a vibration-absorbing roller and a braking roller upstream or/and downstream to a mark detector in the direction of forward and backward movement of a sheet so that these rollers act to the sheet when it is quickly stopped. CONSTITUTION:Braking rollers 18, 19 made of a high-friction-coefficient material are provided upstream and downstream to a detector 17 in the direction of movement of a sheet F. When a stop signal is generated by a counter, solenoids SOL4, SOL5 are supplied with electricity to attract braking plates 181, 191 to stop the rotation of the braking rollers 18, 19. The sheet F vibrates when the stop signal is generated by the counter as a result of the detection of a section with a predetermined number during a rapid search. At that time, a vibration- absorbing roller 21 is displaced by the maximum vibration amplitude H1 in the direction of movement of the sheet so that if the downward motion of a rocking arm 27 is insufficient, the sheet is moved in the direction by the quantity of the insufficiency. The vibration of the sheet F is thus absorbed by the motion of the rocking arms 26, 27.

Abstract: PURPOSE:To improve the covering property at both end parts of sheet by a method wherein cutting slits, which enable to cut-off both the end parts of the cover sheet, is made beforehand in the heat shrinkable cover sheet having an integral heater for corrosion preventive covering. CONSTITUTION:A heat shrinkable cover sheet 1 having an integral heater consists in laminating heat shrinkable sheets 4 and 5, the direction of orientation of which is normal to that of electric conductor 2, onto both surfaces of a large number of the electric conductor 2 arranged in parallel in a plane and further laminating a heat bonding agent layer 6 onto the underside surface of the sheet 5. In the cover sheet 1 having the above-mentioned structure, the respective electric conductor 2 are connected with metal wires 7 at the end parts of the sheet and at the same time slits (perforation and the like) 9 and 9' are made at both end parts by means of laser rays or the like so as to be able to cut-off. After said sheet is rolled onto a steel pipe and thermally shrunken, both the end parts 1b and 1c are cut-off. Though uniform heat shrinkage is hard to realize at the end part and accordingly no neat covering is possible at the end part, the cutting-off of the end part eliminates the trouble just mentioned above.
