A maple sap line system and method for spin welding provides secure, unobstructed lines for collecting sap by creating a hermetically sealed connection between a lateral line and a mainline. A fitting connects the mainline to the lateral line. The fitting is spin welded to the mainline at a contact interface. The fitting comprises a protruding member that easily melts to create the frictional weld. The fitting has an elongated body comprising barbs that receive the lateral line. The fitting has a channel that enables fluid communication between the mainline and the lateral line. The flanges in the fitting register with a chuck to rotate the fitting against the main line at a high rpm. Molten debris formed in the channel is dislodged by drilling with a collared drill. The drilling provides fluid communication and creates a smooth inner surface in the mainline, and cuts off flanges from the fitting.

A separating device for separating individual container products from a frame assembly of plastic material, particularly polypropylene, has at least one stamping device (36) that at least partially separates the respective container product from a frame waste. By the stamping device (36) including a free fall body (52) separating the respective frame waste from the associated container product from an initial position during free fall, the separation can be carried out with very high speed (free fall) and additional mechanical components for applying a constraint force on the stamping body during the creating of the separating line can be omitted.

A polymer stall divider for a barn will permit lateral flexing when a cow presses against the stall divider while the stall divider asserts a lateral force against the cow to urge the cow to move into a proper position between adjacent stall dividers without causing injury to the cow. The polymer stall divider can be formed of a polymer material clad onto the outer surface of a steel structural member and then bent into shape to form the desired configuration. The divider can be formed in sections with adjacent sections being connected by an internal connector formed of selected materials to provide the desired flexibility and durability characteristics. A mounting bracket formed of a pair of opposing clam shells can be utilized to secure the stall divider to the frame of the barn, thus providing an easily installed divider structure.

The present invention relates to a process for the production of hollow plastic articles in a rotational molding process as well as to hollow plastic articles made by such a process, in particular to a process for the production of hollow plastic articles which exhibit a colored surface exhibiting striking pearlescent or metallic effects.

A method for producing a tube skirt for a flexible tube, said tube skirt being manufactured from a flat strip 1 comprising a decorative film 15 superimposed on a primary film 16, said primary film 16 comprising a sealable inner layer 14 at the lower surface 20 of the strip 1 as well as two stabilizing layers 11, 13, said decorative film 15 comprising a sealable outer layer 7 at the upper surface 19 of the strip 1, and a decorative layer 8, 9. This method comprises the following steps: winding the flat strip 1 into the form of a sleeve to shape the tube skirt; superimposing a first side border 2 of the strip 1 on a second side border 2 of the strip 1 to form an overlapping area 3, the sealable inner layer 14 of the primary film 16 of the first side border 2 overlapping the sealable outer layer 7 of the decorative film 15 of the second side border 2; applying a heating temperature T2 to the inside of the tube skirt at the inner face 22 of the overlapping area 3 to produce the side weld of the tube skirt; simultaneously with the application of the heating temperature T2, applying compression between the outer 21 and inner 22 faces of the overlapping area 3 so as to finalize the side weld of the tube skirt.
