Abstract:
Knitted netting is applied to products in a machine. A chute receives products serially through a receiving end, as from a conveyor, and discharges them serially into netting preferably rucked on the chute. As each product arrives at the product receiver, voiders operate to form a rope section of the netting behind the product, at the chute's discharge end. The clipper also clips the netting, to complete the netting of the product, and clips to create the starting end of the next netted product. A netting handle former operates to loop the rope section behind the product, before clipping, to form a looped handle for a product in the rope section of the netting. The netting that is clipped behind the products is the netting formed into the loops, and thus, the clips that are put on by the clipper secure the loops in their size and condition. The product receiver is preferably a discharge tray, and product guides on the tray straighten the product, to align it for netting, and also co-operate with the voiders to help tighten the product packaging. The clipper is also preferably uniquely structured in its clip rails to contribute to tighter packaging. The chute is gravity driven and includes product ribs or rails for centering and ease of movement of products. The handle former is an essentially two-part, mechanically actuated disc and clam shell construction that reaches for the netting, captures it, and rotates a loop into it, while tightening the packaging, in co-ordination with the voiders.
Abstract:
An apparatus is provided for filling and sealing flexible poly bags which are provided on a continuous roll. The apparatus has means for heat sealing filled bags. A drive mechanism conveys the bag into position for filling and sealing thereof. A clamp mechanism draws the bags into contact with the heat sealing means during the sealing process. A reverse actuation mechanism is provided for reversing the drive mechanism while the bag remains clamped so as to detach the bag at a perforation thereof. An interrupt means is also provided for disengaging the clamp mechanism when the clamp mechanism is interfered with by a foreign object. The interrupt means consists of an electrical circuit established through the clamp mechanism frame which circuit is broken when the clamp mechanism contacts a foreign object. Also provided is a guide mechanism for guiding the bags into engagement with the drive mechanism. The guide mechanism includes a pair of rollers which are in frictional contact with a table member, and a pair of belts are drivingly connected between the rollers and the drive means.
Abstract:
The invention relates to a device for obtaining a strip of photosensitive material totally enveloped in a light-tight way. The device comprises a light-tight box provided with two openings which allow the strip to pass therethrough; a cutting member for cutting the strip at a distance D from its end; a connecting member for solidly connecting in a light-tight way and without contact between them, the strip of length D and the rest of the strip coming from the reel using a light-tight material applied to both faces of each strip; and a linking member for linking up the material present on one face and the material present on the other face between the two strips.
Abstract:
In contrast to typical machines though, the present invention discloses a device which allows the plate to "float" within the mechanism, so that any inaccuracies in dimensional tolerances between plate and knife are absorbed in a damping of the plate or bed of the mechanism. In this situation, the depth of the cut of the score line can be very reliably controlled, which results in the repeatable manufacturing of a child resistant, yet senior effective package. There is used a spring pre-load for this plate, which is such that cutting takes place yet, as the tool closes, the plate and package come in "metal to metal" contact, assuring "near perfect" cuts of the blister package. Extremely high tolerances are maintained, assuring packages which pass all levels and types of QA testing.
Abstract:
The present invention relates to a machine for slitting continuous tapes o sets of stripes having variously shaped lateral profile, with the possibility of applying cutting cylinders having size as desired, and possibility of modification of the mutual position of the cylinder supporting shoulders, so that tapes can be machined, which have different width, and of the cutting cylinders supporting elements, so to vary the distance between the centers of the said cylinders.
Abstract:
A web 26 of packaging material on which a plurality of cigarette wrapper blanks 10 are defined in oppositely rotated and laterally displaced pairs, is fed between a reciprocatable punch 38 and a fixed support 36 having cooperating cutting edges 39 and counter edges 40, respectively, whereby the downward movement of the punch severs a pair of blanks from the web. The continued downward movement of the punch separates the two blanks of the severed pair through the cooperation of a further cutting edge 45 on the punch and a counter edge 46 on a turntable 41 disposed beneath the fixed support. The turntable is then rotated 180.degree. to successively feed the separated blanks to a suction conveyor 47.
Abstract:
Sheet slitting and punching apparatus for cutting a large elongate sheet of paperboard or similar material into a plurality of rectangular cards of uniform size and punching holes in each of the individual cards. A large sheet is fed along a conveying means having two tandemly arranged feed sections separated from each other by a transverse and a longitudinal slitting station. Both feed sections of the conveyor are driven from a common drive means, however, the upstream or infeed section is driven at a conveying speed substantially slower than that of the downstream or outfeed section. Transversely spaced slitters form longitudinally extending slits in the sheet as it is fed along the conveying means. When the feeding end of the sheet reaches a predetermined location near the upstream end of the outfeed conveyor, it engages a sensing element which immediately stops the conveyor drive. While the conveyor drive is stopped, a transverse slitting member is driven transversely across the sheet from one side to the other and a punch assembly is actuated to punch holes in each of the cards so formed. At the conclusion of a transversely slitting and punching operation, the conveyor drive is restarted and that portion of the sheet downstream from the transverse cut is carried forwardly away from the advancing sheet by the higher speed of the outfeed conveyor section so that the newly formed leading end of the sheet can actuate the sensing means when it arrives at the predetermined location on the outfeed section.
Abstract:
In package-forming apparatus for individually packaging elongated articles such as small sausages between opposing, continuous webs of sealable film means are provided for completely separating or cutting out groups of the individually packaged articles while partially severing the articles in each group for ready separation from each other. In a preferred embodiment a predetermined number of these packaged articles, e.g. five, is completely severed with each of the five articles in the group being partially severed from each other along a readily separable line of perforation. The mechanism for severing and perforating the individually packaged articles is mounted around the periphery or rim of a wheel structure disposed for rotation over the discharge end of the upper run of an endless chain of lower die plates having cavities for receiving the lower portions of each individual article.
Abstract:
Method wherein guide means ''''track'''' a continuous thickened profile formed along the top edge portion of a chain of bag elements to accurately guide the bags as the same are advancing into the apparatus for filling. Such a profile can comprise a bag fastener such as a continuous bead receivable in a groove member, the fastener normally being associated with freely spreadable flaps between which the bag elements are filled. The guide means are preferably assisted by opposed continuous belts movably supporting the bags along the flap region thereof. The belts can further cooperate with collapsible spout means for separately gripping the flaps, and employing the same as tab means to open the fastener for filling; and the fastener is later automatically closed such as between a pair of grooved pressure rollers.
