Title: Cutting and aligning device for sheet material
Inventor: SAKAMOTO NORIO
IPC: B65H5/10
Filed: 1985-11-13
Abstract: PURPOSE:To arrrange sheet materials at intervals of a given distance so as to be convinient for the feed of the sheet material to a next process, by a method wherein the sheet material is fed in proper orientation to a roll cutter to correctly cut it to a specified size. CONSTITUTION:Sheet materials 1 are intermittently fed to a position in the vicinity of the leftment end of an inlet guide 3, and a foirced pusher 5 is horizontally moved forward to move forward the sheet material 1. Through repetition of horizontal forward movement, lowering, backward movement, and raising of a moving table 51 of the forced pusher 5, the sheet material 1 is intermittently moved forward at a prescribed stroke. Forward movement of the forced pusher 5 causes pushing of the sheet material 1 by means of a push claw 50 to feed the sheet material to a roll cutter 2. When the tip of the sheet material 1 is bitten through by each cutter blade, the sheet material 1 is fed as it is cut through the rotation force of the roll cutter 2. The sheet material 1 is cut into five cut pieces, each having a specified width, and selvedges at both ends with the aid of the roll cutter 2, but the selvedges on both sides are removed through a selvedge removal chute, and the five cut pieces enter the passage of an outlet guide 4.

Abstract: PURPOSE: To reduce the consumption of electric power by laying out a dust concentration sensor in an area which demands for ventilation during the construction of a tunnel and computing a ventilation capacity and time based on pressure loss of an air duct and controlling the rotational speed of a fan. CONSTITUTION: The size (d) of a ventilation air duct 4 and the length (L) of the air duct equivalent to the excavation length of a tunnel and its material are measured and their measured results are inputted into a control device 11.
