Abstract:
A needle array (30) suitable for perforating a fibrous preform includes a backplate (32) and a plurality of needles (26) individually removably attached to and extending away from the backplate (32). Each of the plurality of needles (26) includes a bundle (14) of ceramic filaments, a metallic sheath (20) surrounding a first end of the bundle (14) abutting the backplate (32), and a sharpened point (24) on the second end of the bundle (14), the second end being oppositely disposed from the first end.
Abstract:
Disclosed is a punching apparatus, for a coil bound notebook, which divides into many an object to be bound such as a notebook, a book, an album and the like, then punches same while sequentially moving same and enables easy feeding of the object to be bound, for which the punching has been completed, to a subsequent coil binding position. A punching apparatus for a coil bound notebook, according to the present invention, has first and second alignment plates which are provided on a table on which an object to be coil bound is placed, a punch for punching into the object to be bound binding holes into which a coil spring is inserted, and a moving means for the object to be bound for moving the object to be bound to and from the punch. The moving means for the object to be bound comprises: a main body having a lower plate which is mounted on a support, a vertical plate which is fixed on the lower plate, and an upper plate which is fixed on the vertical plate so as to have the central part open; an LM guide having a rail which is fixed on the main body and a block which is coupled to the rail; a saddle which is fixed on the block of the LM guide and has a plurality of step layers formed on one side; a plurality of unit moving units which have formed thereon clips, dividing the object to be bound and holding single sheet bundles, to become sequentially higher and each of which is mounted on each of the step layers of the saddle; and a saddle moving unit which has a supporting plate fixed on the saddle, a first cylinder of which an operating shaft is fixed on the supporting plate, a fixing plate for fixing the rear of the first cylinder, and a screw rod for screw coupling one side of the fixing plate, coupling a handle to the front end and rotatably mounted on frontal and rear supporting plates fixed on the main body.
Abstract:
An apparatus comprises an operating unit (31; 58; 131), which can be a welding unit (31; 131) for welding a closing film (22) to an edge zone (41) of a containing element (3) or a separating unit (58) for separating containing elements (42) from portions of sheet material (62), said apparatus (21; 61; 81; 161) comprising a control unit (CU2; CU3) programmed to enable said operating unit (31; 58; 131) to process selectively a continuous strip of containing elements (3; 42) or discrete groups (118) of containing elements (3; 42).
Abstract:
The method of labelling the food wrap roll consists in unwinding the label in the form of a ribbon (1) from the unwinding roller (2) and feeding it to the tensioning and perforating roller (3), which is located beneath the unwinding roller (2), the roller (3) featuring at least one bushing tube (11) with the needles (12) and puncturing perforation holes (15) along the label ribbon (1), and the label ribbon (1) is fed through a set of guide rollers (4), wound on the rolled up food wrap roll (5) and cut off crosswise. The perforation device of the labelling machine comprises the rollers (16) with bearings, mounted pivotally on the axle (13), and at least one bushing tube (11) mounted coaxially in between, with the needles (12) attached on the outer circumference and projecting out the circumference of the rollers (16), wherein the axle (13) mounted on the holders (19), attached to the frame of the labelling machine (17), is detachable. The label wound on the food wrap roll, characterised in that it features at least one row of perforation holes (15).
Abstract:
Dispositif (1), destiné à l'ouverture de sacs, notamment de sacs contenant des matériaux pour l'agriculture et l'industrie, le dispositif (1) comprenant un axe central (2) dont une portion supérieure comprend au moins une pointe (5) adaptée pour percer un sac, le dispositif (1) comprenant en outre au moins une lame (3) adaptée pour trancher un sac et solidarisée à une portion inférieure (8) de l'axe central (2), chaque lame (3) présentant un fil orienté du coté de la portion supérieure de l'axe central (2).
Abstract:
Apparatuses for forming discrete deformations in web materials are disclosed. The apparatus may be in the form of nested or other arrangements of multiple rolls, in which the web is maintained in substantial contact with at least one of the rolls throughout the process, and at least two of the rolls define two or more nips thereon with other rolls. In some embodiments, rolls can be used to expose a different side of the web for a subsequent deformation step. In these or other embodiments, the rolls can be used to transfer the web between rolls in such a manner that it may offset the rolls and/or web so that subsequent deformations are formed at a different cross-machine direction location than prior deformations.
Abstract:
A method for making apertures in a precursor web using a forming apparatus is provided where the web comprises a film having molecular orientation and the forming apparatus comprises an arrangement of teeth. The orientation of the arrangement of teeth and the molecular orientation of the film are predetermined and modified to provide a relative angle between the orientation of the teeth and the molecular orientation of the film. Apertures formed in the precursor web material have a length and width exhibiting a minimal aspect ratio.
