Printing materials elevator

A printing materials elevator for raising and lowering printing materials and used in a rotary press which consists of multi-layered printing sections and which has an upper work floor corresponding to an upper printing section and a lower work floor corresponding to a lower printing section, comprising:

• a left upper turning body and a right upper turning body installed at a high level on an upper story containing the upper work floor, opposing each other at an interval larger than the width of the printing materials;
• a left lower turning body and a right lower turning body installed at a low level on a lower story containing the lower work floor, opposing the upper turning bodies vertically and opposing each other at the same interval as the upper turning bodies;
• a left endless flexible body having rear and front segments looped over the left upper and lower turning bodies and a right endless flexible body having rear and front segments looped over the right upper and lower turning bodies;
• drive means for rotating the turning bodies so as to run the left and right endless flexible bodies all at once;
• and
• press plate holding means which has a plurality of press plate holders installed at an angle and at predetermined vertical intervals and which is disposed between the left and right endless flexible bodies with a left side of the press plate holding means being connected to the rear segment of the left endless flexible body stretched between the upper and lower turning bodies and a right side of the press plate holding means being connected to the rear segment of the right endless flexible body stretched between the upper and lower turning bodies;
• roller holding means wherein roller holders which can hold a print roller outside the travel area of the press plate holding means are connected to the front segments of the left and right endless flexible bodies.
