An airflow control apparatus for a tenter oven including an entrance into which a film is conveyed and an exit from which the film is taken out, the airflow control apparatus having a box-shaped body installed adjacent to at least one or both of an upstream side in a film running direction of the entrance and a downstream side in the film running direction of the exit, includes: at least one pair of air blowing nozzles configured to blow air toward the film; at least one pair of upstream-side exhaust mechanisms configured to discharge air in the box-shaped body, and located on the upstream side of the air blowing nozzles in the film running direction; and at least one pair of downstream-side exhaust mechanisms configured to discharge the air in the box-shaped body, and located on the downstream side of the air blowing nozzles in the film running direction.

A link mechanism 11 includes a pair of rail holders 24. The rail holders 24 include guide rollers 51a, 51b, 52a, and 52b configured to move along rails 13 and 14 while rotating, roller shafts 54 and 55 penetrating the guide rollers 51a, 51b, 52a, and 52b, bearings 56a, 56b, 57a, and 57b interposed between the guide rollers 51a, 51b, 52a, and 52b and the roller shafts 54 and 55 and rotatably supporting the guide rollers 51a, 51b, 52a, and 52b, and lower cover members 71 and upper cover members 72 provided on both end sides of the guide rollers 51a, 51b, 52a, and 52b in an axial direction and covering the bearings 56a, 56b, 57a, and 57b.

A longitudinally curved support rail (56) for supporting and moving a drive chain assembly (52) at the base of a spiral conveyor belt (34) to drive the bottom tier (30) of the spiral conveyor belt while being supported by the support rail. The support rail including an upright web section (80) and a support flange (78) cantilevered outwardly from the web section to provide a platform or shelf to support a chain drive assembly (52), thereon during travel of the chain drive assembly along the support rail.

A solid lubricant 11 is formed by molding and firing powder that includes amorphous and self-sintering carbon material powder 12, graphite powder 13, and a binder 14. The solid lubricant has high material strength and hardness, and also excellent impact resistance and wear resistance.

A polyolefin packaging film is provided. The polyolefin film is formed by a thermoplastic composition containing a continuous phase that includes a polyolefin matrix polymer and nanoinclusion additive is provided. The nanoinclusion additive is dispersed within the continuous phase as discrete nano-scale phase domains. When drawn, the nano-scale phase domains are able to interact with the matrix in a unique manner to create a network of nanopores.

An improved linear-motor-operated conveying system is distinguished, inter alia, by the following features: the conveyed web can be fixed to the nipper part, as a result of which a conveyed web plane is defined, said film plane being arranged at a height with respect to the motor working side of the single linear motor drive or of the more powerful linear motor drive in the case of two linear motor drives, and said height being less than or equal to the length of the secondary parts on the conveying parts; the conveying system comprises either a) only one linear motor drive provided beneath the conveying part, or b) only one linear motor drive provided above the conveying part, or c) one linear motor drive arranged beneath and one arranged above the conveying part, the upper linear motor drive and/or the associated control system being configured in such a manner that the upper linear motor drive can only be operated with a maximum power of 75% in relation to the maximum power of the lower linear motor drive.
