Abstract:
Provided is a method for producing a separator which method less causes a tear in the separator. The method is a method for producing a separator by slitting, in a direction in which a separator original sheet (12b) being porous is conveyed, the separator original sheet (12b) into a plurality of separators (12a), including the steps of: (a) conveying the separator original sheet (12b) in a state where the separator original sheet (12b) is in contact with a roller (77); and (b) slitting the separator original sheet (12b) at a portion where the separator original sheet (12b) is in contact with the roller (77).
Abstract:
A curtain cutting machine contains: a base, a first cutting mechanism, and a movable platform. The base includes a fixed platform having a front segment and a rear segment. The first cutting mechanism includes a lower cutting assembly with plural first orifices and has an upper cutting assembly with at least one second orifice. The movable platform includes two support racks, two slidable adjusting devices, and a holding plate. The two support racks are arranged on a rear side of the fixed platform of the base and extend upwardly, each of the two slidable adjusting devices is mounted on each of the two support racks and moves forward and backward on each of the two support racks, the holding plate is connected with each slidable adjusting device to hold a curtain, and the holding plate moves forward and backward on the two support racks with the two slidable adjusting devices.
Abstract:
A wrinkle or misaligned winding caused in a separator roll is inhibited. A slitting apparatus (6) includes (i) a first touch roller (81U) whose position is changed in accordance with a change in outer diameter of a first separator roll (12U), which is formed on a core (u), so as to press the first separator (12a) onto a take-up surface of the first separator roll and (ii) a first take-up assisting roller (83U) which conveys the first separator immediately before the first touch roller and whose position is changed in accordance with positional change of the first touch roller.
Abstract:
A wrinkle or misaligned winding caused in a separator roll is inhibited. In a slitting apparatus (6), a conveying direction of a first separator (12a) is changed to a first take-up roller (70U) side by a direction changing roller (68), the first separator is conveyed via a take-up assisting roller (69) which is provided between the direction changing roller and a first touch roller (81U) so as to shorten a roller-to-roller distance to the first touch roller, and the first separator which is being wound is pressed onto a take-up surface by the first touch roller.
Abstract:
It is intended in an apparatus for successively making plastic bags that a plastic film 1 is cut by a Thomson blade 3 without making the Thomson blade 3 pressed with a large force. The Thomson blade 3 is brought into contact with the plastic film 1 on one of opposite sides of the plastic film 1 in a direction of thickness thereof while a rolling member 4 is brought into contact with the plastic film 1 and rolled and moved along the plastic film 1 and the Thomson blade 3 on the other side of the plastic film 1 in the direction of thickness thereof. The plastic film 1 is therefore sandwiched between and cut by the Thomson blade 3 and the rolling member 4 to successively make plastic bags.
Abstract:
A tape cutting device includes a main body having a slot for guiding the tape therethrough. At least one finger is hingedly connected to the main body adjacent the slot, and a blade attached to the finger at a surface closest to the slot. A method of cutting a strip of tape includes moving the strip of tape through a main body along a path, and selectively pressing one or more fingers which each support a blade to move the blade into the path.
Abstract:
Devices for cutting interconnected plastic products for use in the medical sector provided in a continuous band of plastic, comprising a laser, a laser control system and an optical acquisition and data processing unit are disclosed. Devices for the manufacture of plastic products, such as fillable or filled plastic containers for use in the medical sector, comprising a device for cutting interconnected plastic products provided in a continuous band of plastic as well as a process for cutting interconnected plastic products provided in a continuous band of plastic are disclosed. The optical acquisition unit may determine positional data for the interconnected plastic products provided in the band. From the positional data a cutting pattern may be calculated and transmitted to the laser control system. According to this cutting pattern, the position, intensity and focal point of the laser may be controlled by the laser control system, which may comprise a focusing optic, a deflection means and a beam-forming means.

Abstract:
Provided are a device and a method for ripping gum of a conveyor belt in which the workload of workers and danger to the workers can be reduced, and gum around each of the steel cords can be cut off nearly completely and sufficiently uniformly, regardless of skill of workers, as well as, the work efficiency is more favorable than before.Provided is a device for ripping gum of a conveyor belt in which individual steel cords embedded in gum of a conveyor belt are separated between each other, and gum is stripped off around each of the steel cords after the separation. The device includes a V-shaped cutting blade having a shape such that the upper end and the lower end of the cutting blade are protruded with respect to the traveling direction of the conveyor belt for separating between the individual steel cords, and a cylindrical cutting blade for stripping gum off around each of the steel cords.
Abstract:
Described is a method of making a laminated paint roller wherein a perforated strip of thermoplastic material is advanced, the perforated strip having holes there-through. A lubricant is applied to the inner surface of the advancing perforated strip of thermoplastic material. The lubricated, perforated strip of thermoplastic material is helically wound around a cooled mandrel so as to form a helically wound strip wherein the inner surface of the perforated strip faces the cooled mandrel and the outer surface of the perforated strip faces away from the cooled mandrel. The wound perforated strip is advanced along the cooled mandrel. A layer of adhesive is applied onto an outer surface of the wound perforated strip. A strip of composite cover material is helically wrapped about the wound strip and over the layer of adhesive, the outer surface of the composite cover material comprising a pile fabric, and the inner surface of the composite cover material comprising thermoplastic. A compressive force is applied upon the composite cover material to urge the composite cover material, the layer of adhesive and strip of thermoplastic material together against the cooled mandrel, thereby laminating the inner surface of the composite cover material to the outer surface of the strip. A method of making a composite cover material is also disclosed.
