A sheet dispenser system having a roll of sheet material and a housing to receive the roll. The roll of sheet material comprises a first end portion incorporating a key, and the housing comprises a mounting portion arranged to support the first end portion of the roll. The mounting portion comprises a lock arrangement which is movable between a locked condition and a free condition. The lock arrangement comprises a rotatable element configured for rotation about an axis, and a locking element configured for engagement with the rotatable element to inhibit rotation of the rotatable element, such that, when the locking element and the rotatable element are engaged, the lock arrangement occupies the locked condition, and when the locking element and the rotatable element are disengaged, the lock arrangement occupies the free condition. The mounting portion is arranged such that the roll is movable between an engaged condition, in which the key engages the mounting portion, and a disengaged condition, in which the key is disengaged from the mounting portion, such that, when the roll is moved from the disengaged to the engaged condition, the first end portion of the roll moves the lock arrangement into the free condition, thereby permitting rotation of the rotatable element. The locking element and the rotatable element are configured for engagement by relative movement of the locking element and the rotatable element towards each other in a direction along the axis of rotation of the rotatable element.

An assembly for an adjustable expansion spool that accommodates various lengths of pipe and can be adjusted in the field to a customized length to connect two pipes. One embodiment of the adjustable expansion spool has a main body that has one end inserted into a first connection box and a second end inserted into a second connection box. Both the first connection box and the second connection box can be capable of being coupled to a first flange and a second flange respectively. Both flanges encircle the main body and have an annular groove. Housed between the flanges and a ring groove on the main body is a ring. By adjusting the length between the second flange and a peripheral flange on the second connection box, the adjustable expansion spool can be expanded or contracted, depending on the needs of the user on site in the field.

A scarf-joint structure for the paper tube of a film dispenser is mounted in a film dispenser, which includes a frame connected with a film installation unit and an adjustment unit. The film installation unit is installed with a film roll and consists of a first positioning member and a second positioning member. The adjustment unit is formed with an operating part and a connecting part, and the operating part is connected with an adjusting member, which is threadably fixed with a screw fastener and further, an elastic member is mounted between the operating part and the connecting part. Thus, the film roll, the first positioning member and a second positioning member can be rotated synchronously, able to prevent the film roll from running idle, causing dislocation and falling off.

A pair of flanges attachable to the arbor hole of a reel is disclosed. The flanges provide a mechanism to allow the reel to be easily loaded, and lifted into place. Once loaded into place, the flanges may include a locking mechanism that locks the reel in place, centered on the flanges. Additionally, the flanges are attachable using a hub that allows them to rotate independently from one another, and from the reel to which they are attached.

The present invention refers to a cooling control system of a coiling mandrel (102; 202; 302; 402; 502; 602) for metal products which comprises: an internal shaft (108; 308) with a plurality of sectors (109); an external drum which as a whole contains coaxially said internal shaft and which is circumferentially subdivided into a plurality of segments (104) arranged in a direct or indirect coupling connection with said sectors; and an internal and/or external cooling system of the mandrel The segments are movable in a radial direction with respect to said internal shaft through an axial movement of the latter, causing the consequent radial expansion or collapse of the drum. The mandrel is further provided with a group of temperature detection sensors (130, 132, 134, 136; 234, 236; 332, 336; 43N; 53N; 63N; 3N). A method for monitoring and adjusting the temperature of a coiling mandrel is also described.

A sheet product dispenser for dispensing sheet product from a roll of sheet product is provided. An example sheet product dispenser includes a housing defining an interior space for receiving a first roll of sheet product (170a, 170b) therein, a mandrel (150a, 150b) positioned within the interior space, and a spindle (100) positioned over at least a portion of the mandrel and configured to support the first roll of sheet product for rotation about the mandrel The spindle comprises abase portion (102) and a nose portion (104) configured to translate relative to one another along a longitudinal axis of the mandrel (150a, 150b). At least a portion of the spindle is configured to translate relative to the mandrel from a first configuration to a second configuration to cause a remainder of the first roll of sheet product (170a, 170b) to deform and enable movement of a dispensing door (186) to enable access to a second roll of sheet product.

A method for automatically replacing reels in an unwinding assembly capable of carrying out the handling operations of the reels, as well as preparing and joining the tail of the web of the finished reel with the head of the web of the new reel in a simple, efficient way, reducing the risk of malfunctions and maintaining the correct orientation of the new web as that of the finished web.

An expandable pipe spool operable to connect components of a hydrocarbon extraction assembly is provided. The expandable pipe spool includes a female pipe segment having an outer surface and an inner surface having at least one sealing groove; at least one fluid port on the outer surface of the female pipe segment for receiving a hydraulic fluid, the fluid port in fluid communication with the sealing grove; a male pipe segment having an outer surface receivable within the female pipe segment; a sealing member positioned within the sealing groove between the inner surface of the female pipe segment and the outer surface of the male pipe segment; and a fastening arrangement to lock the male pipe segment in a selected longitudinal position with respect to the female pipe segment.

A reel system that includes a drum that receives a coil of flexible pipe. A first flange that removably couples to a first side of the drum. A second flange that removably couples to a second side of the drum. The first flange and the second flange secure the coil of flexible pipe to the drum.

A telescoping cable spool for attaching to a networking equipment and supporting a plurality of fiber optic cables is shown. The spool comprises a fixed part for attachment to a surface adjacent the networking equipment; a spool housing comprising a pair of cable retaining flanges interconnected by a hollow cable support dimensioned to fit in a telescoping arrangement over the fixed part. The spool housing is moveable relative to the fixed part between a first retracted position and a second extended position.
