A mechanical restraint member for retaining the relative position of a first conduit in a piping system relative to a second conduit in the piping system. The mechanical restraint member has a flexible substrate having a first outer side, a second inner side and first and second axially spaced apart ends, and a first bonding agent provided on at least a portion of the second inner side.

A film edge sealing device is disclosed herein which has a groove defining a base. The base of the groove of the edge sealing device is oriented at a skewed angle with respect to a longitudinal direction of the conveyor of the heat sealing machine. Edges of a thermoplastic sheet or two stacked layers of thermoplastic sheets are introduced into the groove of the edge sealing device and placed in contact therewith to both heat and melt the edges of the thermoplastic sheet(s) to form a bead and join the edges thereof to form an edge bead seal.

An off-axis prepreg material manufacturing machine may include a robot configured to position a prepreg piece adjacent to an end of a prepreg layer. The machine may additionally include an alignment system configured to sense a position of the prepreg piece relative to the prepreg layer and generate a position signal representative thereof. The machine may also include a controller configured to receive the position signal and cause the robot to adjust the position of the prepreg piece such that an end edge of the prepreg piece and an end edge of the prepreg layer are in substantially abutting contact.

The present disclosure relates to a method for producing an oral pouched snuff product comprising a filling material (29, 10) and a saliva-permeable pouch (43) enclosing the filling material (29, 10), the product (29, 10) having a moisture content of at most 20% by weight, in particular at most 10% by weight, based on total weight of the product (29, 10), the saliva-permeable pouch (43) having one or more seals (45, 46), and said filling material (29, 10) comprising at least 20% by weight, based on dry weight of the filling material (29, 10), of at least one ingredient having a melting temperature below 180 C., the method comprising ultrasonically welding and cutting an advancing web (32) of packaging material (7) to which the filling material (29, 10) has been supplied. The present disclosure also provides an oral pouched snuff product which is obtainable by this method.

A device for welding profiled elements in plastic material includes: a base frame supporting retaining members of respective profiled elements, to engage the profiled elements with corresponding zones to be welded facing one another; a heater for heating the weld zones of the profiled elements; a unit to move the retaining members, to shift the profiled elements between a first reciprocal away direction and a second reciprocal closer direction wherein the zones to be welded are coupled together; and a removal unit utilizing milling The removal unit includes: a supporting frame positioned in correspondence to the retaining members; at least one machining tool; a motor part associated with the tool; and a movement member of the tool, to move it between a first idle condition and a second working condition wherein it is placed between the profiled elements.

A method for welding profiled elements in plastic material, includes the steps of: preparing two profiled elements, arranged with respective zones to be facing one another; making a groove in correspondence to at least one zone, by a removal operation on a peripheral edge of at least one profiled element; heating the zones to be welded; coupling the zones to be welded to one another, pressing the profiled elements one against the other so as to keep the zones to be welded in reciprocal contact. The coupling step includes: melting the zones to be welded into one another in order to define a welding bead; making a containing compartment defined by the groove, the welding bead being made internally of the containing compartment; and arranging a containing presser in correspondence to the containing compartment for preventing exit of the welding bead from the compartment itself.

A method for welding profiled elements in plastic material includes: preparing two profiled elements, arranged with respective weld zones facing one another; making a groove corresponding to at least one weld zone of the profiled elements, the grooving performed by a removal operation on a peripheral edge of at least one profiled element; heating the weld zones; coupling the zones to be welded to one another, pressing the profiled elements together to keep the zones to be welded in reciprocal contact. The coupling step includes: a sub-step of melting the zones to be welded into one another in order to define a welding bead; a sub-step of making a containing compartment defined by the groove, the welding bead being made internally of the containing compartment; and the step of arranging a containing presser in correspondence to the containing compartment for preventing exit of the welding bead from the compartment itself.

A sealing station configured to heat seal a wall made from heat-sealable film material, preferably metal-free heat-sealable film material, onto one another wall of heat-sealable material, e.g. another wall of heat-sealable film material, to create a sealed seam. The sealing station comprises an impulse sealing device comprising a first jaw and a second jaw, wherein at least the first jaw comprises at the respective front surface thereof at least one, e.g. a single elongated, impulse heatable member that extends along the respective front surface and that is covered by a heat-resistant non-stick covering.

A hollow fiber membrane fluid transport device is disclosed wherein the fibers are comprised of Polytetrafluoroethylene (PTFE), and the potting materials are comprised of fluorocopolymer and or fluoroterpolymer based materials. The potting of the device utilizes a compressed chemically resistant fluorocopolymer and or fluoroterpolymer film, allows for ease of manufacture without destruction of the PTFE hollow fibers, with high packing densities, and without the processing complexity of pre-melting, extruding, or chemical crosslinking of any polymeric adhesives. Furthermore, the PTFE hollow fibers can be treated with a fluoropolymeric solvent solution before the chemically resistant film is applied to enhance the adhesion of the PTFE fiber to the film. PTFE hollow fibers, and its respective fluoro-co and terpolymers as potting films impart high packing densities, superb chemical resistance and temperature resistance without membrane contamination, or low fiber pull strength, as is sometimes observed with standard potting materials such as polyurethane and epoxy.
