“'KICK' HAD GONE OUT OF DYNAMITE,” Kingston Whig-Standard. February 24, 1933. Page 1. ---- Sticks Found at Welland Canal Likely Stolen and Buried in Rocks ---- ST. CATHARINES, Feb. 24 - Test at the laboratory at Queenston quarries of the dynamite discovered yesterday near the Welland Canal showed that most of the "kick" had gone out of the sticks through age and exposure to weather. Thirteen sticks unaccounted for are believed to have been found in granular condition by boys and scattered about the grass and rocks.

The box holding yesterday's find shows this dynamite was of a lot used many months ago. It had apparently been stolen from one or several contracting companies, left buried in the rocks and forgotten or left behind by thieves.

Chief Harold said today so far as he is concerned the case is closed.

Raw Material Preparation:

The manufacturing process begins with the selection and preparation of raw materials. Grey back duplex board typically uses recycled fibers as the base material. These fibers are sourced, sorted, and cleaned to remove impurities and ensure uniform quality.

Pulping:

The cleaned fibers are then pulped by mixing them with water and chemicals in a pulping machine. This process breaks down the fibers into a slurry, which is refined to achieve the desired fiber characteristics such as strength and smoothness.

Paper Formation:

The pulped fiber slurry is fed into a papermaking machine, such as a Fourdrinier machine or a twin-wire machine. On this machine, the slurry is deposited onto a continuous wire mesh where water drains away, and the fibers start to bond together to form a wet sheet of paper.

Pressing:

After formation, the wet paper sheet passes through presses that squeeze out more water and compress the fibers to increase the paper’s density and strength. This step also helps in achieving the desired thickness of the paper.

Coating Application:

Once pressed, the base layer of the duplex board is coated on one side with a layer of coating material. In the case of grey back duplex board, this coating typically consists of a mixture containing recycled fibers and other materials to achieve the grey color and enhance stiffness.

Drying:

The coated duplex board then passes through drying cylinders or ovens to remove moisture and solidify the coating. Proper drying is crucial to ensure the board reaches the desired moisture content for optimal performance in subsequent processing and applications.

Calendering (Optional):

Depending on the desired finish, the dried duplex board may undergo calendering. This involves passing the board through rollers to further smooth the surface and improve its finish, enhancing printability and appearance.

"NEWSPRINT MEN ON STRIKE AT FORT FRANCES," Winnipeg Tribune. May 1, 1934. Page 3. --- Management Rejects Plea For 36-Hour Week and Guarantee of Employment ---- [Special to The Winnipeg Tribune] FORT FRANCES, Ont., May 1- Three thousand pulp and paper mill employes of this town are on strike today as a result of the dead-lock in negotiations between the pulp and paper companies and their mill employes. The strike became effective at 8 a.m., when no mill employes responded to the whistle summoning them to work.

There is no sign of disorders. The men are quietly walking the streets and the companies are making no attempt to operate with out- side help.

The companies have been negotiating with their employes for some time. The men are receiving 35 cents an hour basic wage for a 48-hour week on an annual contract which expired on April 30. The employes ask a substantial increase in pay, a 36-hour week, and an employment contract.

Officials of the company have not indicated what their counter- proposals are, other than to say that they have offered an increase in pay with an annual contract. They say that, with the newsprint market in the present uncertain shape, there must be leeway for employment readjustments to meet any situation which may develop. There is no objection, apparently to an annual contract, but the employers do not acquiesce in the plea for a long-time wage contract.

The two companies affected are the M. and O. Paper Company, International Falls, and the Fort Frances Pulp and Paper Company, of Fort Frances. R. Andrews has been conducting the negotiations for the management and union officials have conducted the case for the men.
