Description

Technical Field

[0001] This invention relates to the field of glass wool production technology, and in particular to a device for trimming excess edges in glass wool production. Background Technology

[0002] In the production process of glass wool, the glass raw materials are first melted at high temperature. The molten glass is centrifuged and fiberized through a centrifugal system, and finally enriched on the conveyor belt to form glass wool. The glass wool is transported by the conveyor belt and continuously laid flat on the conveyor belt. After solidification, it forms glass wool with a certain width. Then, the excess edges on both sides of the glass wool need to be cut off, and the glass wool is then cut crosswise to form glass wool segments. Finally, the glass wool is rolled up and packaged for sale.

[0003] During the process of trimming excess glass wool, it is necessary to ensure the neatness of both sides of the glass wool and to maintain its width. The traditional cutting method involves fixing two circular saws above the conveyor belt to cut the glass wool. This method is inconvenient for adjusting the width of the two circular saws. Every time the production line adjusts the production width of the glass wool, the equipment designer needs to spend a lot of time adjusting the distance between the two circular saws, which is very inconvenient. Moreover, when trimming the excess glass wool, the waste material usually accumulates on both sides of the conveyor belt. If there is too much accumulation, the glass wool fragments will become entangled in the conveyor belt and enter the next process, affecting the packaging of the finished glass wool. Therefore, an excess trimming device is needed to solve this problem. Summary of the Invention

[0004] The purpose of this invention is to provide an edge trimming device for glass wool production, which has the functions of conveniently adjusting the width, trimming the edge of glass wool, and cleaning up the edge waste.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a glass wool production edge trimming device, comprising a conveyor belt for conveying glass wool, a frame, two sets of circular saws located on both sides of the conveyor belt, a drive mechanism one for controlling the lifting and lowering of the two sets of circular saws and the spacing, and a drive mechanism two for controlling the rotation of the two sets of circular saws. The bottom of the conveyor belt is provided with a crushing mechanism for crushing the glass wool edge, the crushing mechanism including a shearing component for initially cutting the glass wool edge into segments, a crushing component for crushing the segments of glass wool into powder, and a drive mechanism three for driving the shearing component and the crushing component to work.

[0006] By adopting the above technical solution, two sets of circular saws cut the excess edges of glass wool on the conveyor belt. Drive mechanism one controls the raising and lowering of the circular saws. When production starts, the circular saws are lowered to cut the glass wool. When the production line stops, the circular saws are raised to facilitate cleaning of the production line. At the same time, the drive mechanism also controls the distance between the two circular saws to adjust the width of the glass wool and realize the switching of different sizes of glass wool. Drive mechanism two drives the circular saws to rotate, and the circular saws cut the excess edges of the glass wool. The conveyor belt continuously transports the glass wool forward. When the glass wool passes the circular saws, the excess edges of the glass wool will be cut off.

[0007] The cut edges are crushed by a crushing mechanism. The shearing component first cuts the glass wool into small pieces, and then the crushing component crushes the small pieces of glass wool. Finally, the glass wool is transported away by an external transfer device, so it will not accumulate on both sides of the conveyor belt.

[0008] As a further feature of the present invention, the drive mechanism includes a support beam. The frame is vertically arranged on both sides of the support beam with a guide rod, a lead screw, and a motor for driving the lead screw to rotate. One end of the support beam is slidably connected to the guide rod, and the other end is fixedly connected to the lead screw nut. A power assembly is provided on the support beam, and the power assembly drives the two sets of circular saws to move closer or further apart from each other.

[0009] As a further feature of the present invention, the power assembly includes a bidirectional lead screw rotatably connected to the support beam. The bidirectional lead screw is perpendicular to the conveying direction of the conveyor belt. The bidirectional lead screw is rotatably connected to the support beam. The bidirectional lead screw is connected to a second motor that drives its rotation. Connecting beams are fixedly connected to the two lead screw nuts of the bidirectional lead screw. The two circular saws are respectively connected to the two connecting beams.

[0010] As a further feature of the present invention, the bottom of the connecting beam is rotatably connected to a support shaft, and the two circular saws are respectively coaxially fixedly connected to the two support shafts. The second drive mechanism includes a telescopic shaft, a third motor for driving the telescopic shaft to rotate, a first synchronous wheel and a first synchronous belt disposed at both ends of the telescopic shaft and connected to the two sets of support shafts. The telescopic shaft includes a connecting sleeve rotatably connected to the support beam, a first rotating shaft and a second rotating shaft slidably disposed at both ends of the connecting sleeve. The connecting sleeve, the first rotating shaft and the second rotating shaft are coaxially disposed and their axes are perpendicular to the conveying direction of the conveyor belt. The first rotating shaft and the second rotating shaft are respectively rotatably connected to the two sets of connecting beams. The inner cavity of the connecting sleeve is a non-circular irregular cavity. The parts of the first rotating shaft and the second rotating shaft that are slidably connected to the connecting sleeve are non-circular irregular parts. The irregular parts and the irregular cavity cannot rotate relative to each other axially. A first synchronous wheel and a first synchronous belt are disposed between the first rotating shaft and one set of support shafts, and between the second rotating shaft and another set of support shafts.

[0011] By adopting the above technical solution, two circular saws cut the glass wool on the conveyor belt. When the production line stops production and it is necessary to raise the circular saws, the motor controls the lead screw to rotate. The rotation of the lead screw drives the support beam to rise, and the support beam drives the circular saw to rise. Similarly, when the production line starts production, the motor flips and drives the lead screw to flip, which drives the support beam to fall. The support beam drives the circular saw to fall, and the circular saw can cut the glass wool on the conveyor belt.

[0012] When it is necessary to adjust the distance between the two circular saws, the motor rotates in both directions, which drives the double-sided lead screw to rotate in both directions. The double-sided lead screw drives the two connecting beams to move away from or closer to each other. The connecting beams drive the two circular saws to move away from or closer to each other, thereby adjusting the distance between the two circular saws and thus adjusting the width of the glass wool after cutting.

[0013] To avoid affecting the adjustment distance of the two circular saws and to achieve the goal of driving both circular saws to rotate using a single motor, the two circular saws are connected by a telescopic shaft. Motor 3 controls the rotation of the telescopic shaft, which drives the support shaft connected to the circular saws to rotate via timing pulley 1 and timing belt 1, thereby driving the circular saws to rotate. When the adjustment distance needs to be adjusted, for safety, motor 3 is first turned off, and then motor 2 is started to rotate. The two connecting beams move relative to each other. During this process, in addition to driving the circular saws to move relative to each other, the connecting beams also drive rotating shafts 1 and 2 to move away from each other or... The two circular saws move closer to each other, and rotating shaft one and rotating shaft two slide in the connecting sleeve. After the distance between the two circular saws is adjusted, motor three is started. Motor three drives rotating shaft one to rotate, rotating shaft one drives the connecting sleeve to rotate, and the connecting sleeve drives rotating shaft two to rotate, so that the entire telescopic shaft rotates. At the same time, rotating shaft one and rotating shaft two drive two support shafts to rotate through synchronous wheel one and synchronous belt one, so that the two circular saws rotate. The circular saws cut the glass wool, thus realizing that one motor controls the rotation of two circular saws without affecting the adjustment of the distance between the two circular saws.

[0014] As a further feature of the present invention, the crushing assembly includes an outer cover and a crushing roller disposed inside the outer cover. The crushing roller is provided with blades. The inner wall of the outer cover at the crushing roller is an arc shape that matches the crushing roller. Blades are provided on the arc-shaped inner wall of the outer cover. The outer cover is provided with feed inlets on both sides of the conveyor belt. The shearing assembly is disposed at the feed inlet for shearing the excess edge of the glass wool. The bottom of the outer cover is provided with a discharge outlet.

[0015] As a further feature of the present invention, the shearing assembly includes scissors disposed above each feed inlet, the scissors including scissor blades hinged together in the middle, the outer cover having a stroke groove, the direction of the stroke groove being perpendicular to the conveyor belt conveying direction, a limit rod being provided on the hinge portion of the scissors, the limit rod being slidably disposed in the stroke groove, a limit block being provided at the end of the scissor blade away from the feed inlet, the outer cover having a limit groove, the limit groove being parallel to the conveyor belt conveying direction, the limit blocks at the ends of the two scissor blades being slidably disposed in the limit groove, both limit blocks being hinged to connecting plates, the upper and lower connecting plates being hinged together to a pushing block, the outer cover having a sliding groove, the pushing block being slidably disposed in the sliding groove, the two pushing blocks being connected to a pushing assembly, the pushing assembly pushing the two pushing blocks to slide along the sliding groove.

[0016] As a further feature of the present invention, the pushing assembly includes a spring connected to the pushing block, the other end of the spring being fixedly connected to the outer cover, and also includes a cam and a connecting shaft. The central axis of the connecting shaft is arranged parallel to the conveying direction of the conveyor belt. The cam is coaxially arranged with the connecting shaft. The pushing block is connected to a pushing rod, which abuts against the cam. The driving mechanism drives the connecting shaft to rotate.

[0017] As a further feature of the present invention, the driving mechanism three includes a motor four, which is connected to the crushing roller in a transmission manner. One end of the crushing roller and one end of the connecting shaft are both coaxially provided with a synchronous pulley two, and a synchronous belt two is provided between the two synchronous pulleys.

[0018] By adopting the above technical solution, the excess edge cut by the circular saw enters the outer cover through the feed port. The shearing component first cuts the long strip of excess edge into short strips. Then the short strips enter the crushing roller, the crushing roller crushes the glass wool, and the crushed material is discharged through the discharge port, thus completing the crushing of the excess edge. It is then transferred away by an external transfer device, preventing it from accumulating on both sides of the conveyor belt.

[0019] Specifically, motor four controls the rotation of the crushing roller, which crushes the glass wool segments during rotation. Furthermore, the crushing roller drives the connecting shaft to rotate via synchronous belt two and synchronous pulley two. The rotating connecting shaft drives the cam to rotate, which in turn pushes the push rods on both sides. These push rods cause the push blocks to slide back and forth along the slide groove. As the push blocks slide back and forth along the slide groove, they cause the two connecting plates to open and close. Simultaneously, the two connecting plates cause the two limiting blocks to move away from or closer to each other in the limiting groove. The limiting blocks then cause the shear blades to open and close, and the upper limit rod at the hinge of the shear blades to slide back and forth in the stroke groove. When the shear blades close, they move forward to cut the excess glass wool strips in front. When the shear blades open, they retract, allowing the glass wool to fall downwards a certain distance, awaiting the next cut, thus completing the cutting of the excess glass wool into segments.

[0020] The beneficial effects of this invention are:

[0021] 1. Two sets of circular saws cut the excess edges of the glass wool on the conveyor belt. Drive mechanism one controls the raising and lowering of the circular saws. When production starts, the circular saws are lowered to cut the glass wool. When the production line stops, the circular saws are raised to facilitate cleaning of the production line. At the same time, the drive mechanism also controls the distance between the two circular saws, thereby adjusting the width of the glass wool and realizing the switching of different sizes of glass wool. Drive mechanism two drives the circular saws to rotate, and the circular saws cut the excess edges of the glass wool. The conveyor belt continuously conveys the glass wool forward. When passing the circular saws, the excess edges of the glass wool are cut off. The cut excess edges are crushed by the crushing mechanism. The shearing component first cuts the glass wool into small segments, and then the crushing component crushes the small segments of glass wool. Finally, the glass wool is transferred away by an external transfer device, so that it will not accumulate on both sides of the conveyor belt.

[0022] 2. Two circular saws cut the glass wool on the conveyor belt. When the production line stops, raising the circular saws is necessary. Motor 1 controls the rotation of the lead screw, which in turn raises the support beam, causing the circular saws to rise. Similarly, when the production line starts, Motor 1 rotates, causing the lead screw to rotate, which lowers the support beam, causing the circular saws to descend. The circular saws can then cut the glass wool on the conveyor belt. When adjusting the distance between the two circular saws, Motor 2 rotates in both directions, driving the bidirectional lead screw to rotate in both directions. The bidirectional lead screw drives the two connecting beams to move closer or further apart, which in turn moves the two circular saws closer or further apart, thus adjusting the distance between the two circular saws and consequently the width of the cut glass wool. To avoid affecting the adjustment of the distance between the two circular saws and to achieve the goal of driving both circular saws with one motor, a telescopic shaft connects the two circular saws. Motor 3 controls the rotation of the telescopic shaft. The telescopic shaft drives the support shaft connected to the circular saw to rotate via synchronous pulley one and synchronous belt one, thereby driving the circular saw to rotate. When the adjustment distance needs to be adjusted, to ensure safety, motor three is turned off first, and then motor two is started to rotate. The two connecting beams move relative to each other. During this process, in addition to driving the circular saw to move relative to each other, the connecting beams also drive rotating shaft one and rotating shaft two to move away from each other or closer to each other. Rotating shaft one and rotating shaft two slide in the connecting sleeve. After the distance between the two circular saws is adjusted, motor three is started again. Motor three drives rotating shaft one to rotate, rotating shaft one drives the connecting sleeve to rotate, and the connecting sleeve drives rotating shaft two to rotate, so that the entire telescopic shaft rotates. At the same time, rotating shaft one and rotating shaft two drive the two support shafts to rotate via synchronous pulley one and synchronous belt one, so that the two circular saws rotate. The circular saws cut the glass wool, thus realizing that one motor controls the rotation of two circular saws without affecting the adjustment distance of the two circular saws.

[0023] 3. The excess material from the circular saw cutting enters the outer casing through the feed inlet. The shearing assembly first cuts the long strips of excess material into short strips, which then enter the crushing roller. The crushing roller crushes the glass wool, and the crushed material is discharged through the discharge outlet, completing the crushing of the excess material. It is then transported away by an external transfer device, preventing accumulation on the sides of the conveyor belt. Motor four controls the rotation of the crushing roller, which crushes the glass wool segments during rotation. Furthermore, the crushing roller drives the connecting shaft to rotate via synchronous belt two and synchronous pulley two. The rotating connecting shaft, in turn, drives the cam to rotate. During the process, the push rods on both sides are pushed, and the push rods drive the push block to slide back and forth along the slide groove. As the push block slides back and forth along the slide groove, it drives the two connecting plates to open and close. At the same time as the two connecting plates open and close, it drives the two limiting blocks to move away from or closer to each other in the limiting groove. The limiting blocks then drive the scissor blades to open and close, and cause the upper limit rod of the hinge part of the scissors to slide back and forth in the stroke groove. When the scissors close, they move forward to cut the excess glass wool strip in front. When the scissors open, they move backward, allowing the glass wool to fall down a certain distance, waiting for the next cut, thus completing the cutting of the excess glass wool into segments.

Example

[0032] A device for trimming excess material in glass wool production, reference Figures 1 to 5 The system includes a conveyor belt 1 for conveying glass wool, a frame 2, two sets of circular saws 3 located on both sides of the conveyor belt 1, a drive mechanism 1 4 for controlling the lifting and spacing of the two sets of circular saws 3, and a drive mechanism 2 5 for controlling the rotation of the two sets of circular saws 3. The bottom of the conveyor belt 1 is equipped with a crushing mechanism for crushing the excess glass wool. The crushing mechanism includes a shearing component 6 for initially cutting the excess glass wool into segments, a crushing component 7 for crushing the segments of glass wool into powder, and a drive mechanism 3 8 for driving the shearing component 6 and the crushing component 7.

[0033] Two sets of circular saws 3 cut the excess edges of the glass wool on the conveyor belt 1. Drive mechanism 1 4 controls the raising and lowering of the circular saws 3. When production starts, the circular saws 3 are lowered to cut the glass wool. When the production line stops, the circular saws 3 are raised to facilitate cleaning of the production line. At the same time, the drive mechanism also controls the distance between the two circular saws 3 to adjust the width of the glass wool and realize the switching of different sizes of glass wool. Drive mechanism 2 5 drives the circular saws 3 to rotate, and the circular saws 3 cut the excess edges of the glass wool. The conveyor belt 1 continuously conveys the glass wool forward. When passing the circular saws 3, the excess edges of the glass wool are cut off. The cut excess edges are crushed by the crushing mechanism. The shearing component 6 first cuts the glass wool into small segments, and then the crushing component 7 crushes the small segments of glass wool. Finally, the glass wool is transported away by an external transfer device and will not accumulate on both sides of the conveyor belt 1.

[0034] Specifically, the drive mechanism 4 includes a support beam 41. The frame 2 is vertically arranged on both sides of the support beam 41 with a guide rod 42, a lead screw 43, and a motor 44 that drives the lead screw 43 to rotate. One end of the support beam 41 is slidably connected to the guide rod 42, and the other end is fixedly connected to the lead screw nut of the lead screw 43. A power component is provided on the support beam 41, which drives the two sets of circular saws 3 to move closer or further apart.

[0035] The power assembly includes a bidirectional lead screw 45 rotatably connected to the support beam 41. The bidirectional lead screw 45 is perpendicular to the conveying direction of the conveyor belt 1. The bidirectional lead screw 45 is rotatably connected to the support beam 41. The bidirectional lead screw 45 is connected to a motor 46 that drives its rotation. Connecting beams 47 are fixedly connected to the two lead screw nuts of the bidirectional lead screw 45. Two circular saws 3 are respectively connected to the two connecting beams 47.

[0036] The bottom of the connecting beam 47 is rotatably connected to a support shaft 48. Two circular saws 3 are coaxially and fixedly connected to the two support shafts 48 respectively. The second drive mechanism 5 includes a telescopic shaft 51, a third motor 52 that drives the telescopic shaft 51 to rotate, a first synchronous pulley 53 and a first synchronous belt 54 that are set at both ends of the telescopic shaft 51 and connected to the two sets of support shafts 48. The telescopic shaft 51 includes a connecting sleeve 511 that is rotatably connected to the support beam 41, and a first rotating shaft 512 and a second rotating shaft 513 that are slidably set at both ends of the connecting sleeve 511. The connecting sleeve 511, the first rotating shaft 512 and the second rotating shaft 513 are... 513 is coaxially arranged and its axis is perpendicular to the conveying direction of conveyor belt 1. Rotating shaft 1 512 and rotating shaft 2 513 are rotatably connected to two sets of connecting beams 47 respectively. The inner cavity of connecting sleeve 511 is a non-circular irregular cavity. The part of rotating shaft 1 512 and rotating shaft 2 513 that is slidably connected to connecting sleeve 511 is a non-circular irregular part. The irregular part and the irregular cavity cannot rotate relative to each other axially. A set of synchronous pulley 1 53 and synchronous belt 1 54 are provided between rotating shaft 1 512 and a set of support shafts 48, and between rotating shaft 2 513 and another set of support shafts 48.

[0037] Two circular saws 3 cut the glass wool on conveyor belt 1. When the production line stops, and it is necessary to raise the circular saws 3, motor 44 controls the screw 43 to rotate. The rotation of screw 43 drives the support beam 41 to rise, which in turn drives the circular saws 3 to rise. Similarly, when the production line starts, motor 44 rotates, causing the screw 43 to rotate, which in turn drives the support beam 41 to fall. The support beam 41 then drives the circular saws 3 to fall, allowing the circular saws 3 to cut the glass wool on conveyor belt 1. When it is necessary to adjust the distance between the two circular saws 3, it is done by... Motor 2 46 rotates in both directions, driving the bidirectional lead screw 45 to rotate in both directions. The bidirectional lead screw 45 drives the two connecting beams 47 to move away from or closer to each other. The connecting beams 47 drive the two circular saws 3 to move away from or closer to each other, thereby adjusting the distance between the two circular saws 3 and thus adjusting the width of the glass wool after cutting. In order not to affect the adjustment of the distance between the two circular saws 3 and to achieve the goal of driving the rotation of the two circular saws 3 by one motor, the two circular saws 3 are connected by a telescopic shaft 51. Motor 3 52 controls the rotation of the telescopic shaft 51, which is connected by a synchronous pulley 1 and... Synchronous belt 54 drives the support shaft 48 connected to the circular saw 3 to rotate, thereby driving the circular saw 3 to rotate. When the adjustment gap needs to be adjusted, to ensure safety, motor 3 52 is turned off first, and then motor 2 46 is started to rotate. The two connecting beams 47 move relative to each other. During this process, in addition to driving the circular saw 3 to move relative to each other, the connecting beams 47 also drive the rotating shaft 1 512 and rotating shaft 2 513 to move away from or towards each other. The rotating shaft 1 512 and rotating shaft 2 513 slide in the connecting sleeve 511. After the gap between the two circular saws 3 is adjusted, the motor is started again. Motor 3 52 drives rotating shaft 1 512 to rotate, rotating shaft 1 512 drives connecting sleeve 511 to rotate, and connecting sleeve 511 drives rotating shaft 2 513 to rotate, so that the entire telescopic shaft 51 rotates. At the same time, rotating shaft 1 512 and rotating shaft 2 513 drive two support shafts 48 to rotate through synchronous pulley 1 53 and synchronous belt 1 54, so that two circular saws 3 rotate. The circular saws 3 cut the glass wool, thus realizing that one motor controls the rotation of two circular saws 3 without affecting the adjustment of the spacing between the two circular saws 3.

[0038] The crushing assembly 7 includes an outer cover 71 and a crushing roller 72 disposed inside the outer cover 71. The crushing roller 72 is provided with blades 73. The inner wall of the outer cover 71 at the crushing roller 72 is an arc shape that matches the crushing roller 72. The blades 73 are provided on the arc-shaped inner wall of the outer cover 71. The outer cover 71 is provided with feed inlets 74 on both sides of the conveyor belt 1. The shearing assembly 6 is disposed at the feed inlets 74 for shearing the excess glass wool. The bottom of the outer cover 71 is provided with a discharge outlet 75.

[0039] The shearing assembly 6 includes scissors 61 disposed above each feed inlet 74. Each scissor 61 includes scissor blades 611 hinged together in the middle. The outer cover 71 has a travel groove 62, the direction of which is perpendicular to the conveying direction of the conveyor belt 1. A limit rod 63 is provided on the hinged part of the scissors 61, and the limit rod 63 is slidably disposed in the travel groove 62. A limit block 64 is provided at the end of the scissor blades 611 away from the feed inlet 74. A limit groove 65 is provided on the outer cover 71, and the limit groove 65 is parallel to the conveying direction of the conveyor belt 1. The limit blocks 64 at the ends of the two scissor blades 611 are slidably disposed in the limit groove 65. Both limit blocks 64 are hinged to connecting plates 66. The upper and lower connecting plates 66 are hinged together to a push block 67. A slide groove 68 is provided on the outer cover 71, and the push block 67 is slidably disposed in the slide groove 68. The two push blocks 67 are connected to a push assembly, which pushes the two push blocks 67 to slide along the slide groove 68.

[0040] The pushing assembly includes a spring 69 connected to the pushing block 67, the other end of the spring 69 being fixedly connected to the outer cover 71, and also includes a cam 610 and a connecting shaft 613. The central axis of the connecting shaft 613 is arranged parallel to the conveying direction of the conveyor belt 1. The cam 610 is coaxially arranged with the connecting shaft 613. The pushing block 67 is connected to a pushing rod 612, which abuts against the cam 610. The driving mechanism 8 drives the connecting shaft 613 to rotate.

[0041] The drive mechanism 38 includes a motor 481, which is connected to the crushing roller 72. One end of the crushing roller 72 and one end of the connecting shaft 613 are coaxially provided with a synchronous pulley 282, and a synchronous belt 283 is provided between the two synchronous pulleys.

[0042] The excess material cut by the circular saw 3 enters the outer cover 71 through the feed inlet 74. The shearing component 6 first cuts the long strips of excess material into short strips, which then enter the crushing roller 72. The crushing roller 72 crushes the glass wool, and the crushed material is discharged through the discharge outlet 75, completing the crushing of the excess material. It is then transported away by an external transfer device, preventing it from accumulating on both sides of the conveyor belt 1. The motor 81 controls the rotation of the crushing roller 72, which crushes the glass wool segments during rotation. Furthermore, the crushing roller 72 drives the connecting shaft 613 to rotate via the synchronous belt 83 and the synchronous pulley 82. The connecting shaft 613 drives the cam 610 to rotate during rotation. During the process, the push rods 612 on both sides are pushed, and the push rods 612 drive the push block 67 to slide back and forth along the slide groove 68. As the push block 67 slides back and forth along the slide groove 68, it drives the two connecting plates 66 to open and close. At the same time as the two connecting plates 66 open and close, it drives the two limiting blocks 64 to move away from or closer to each other in the limiting groove 65. The limiting blocks 64 then drive the scissor blade 611 to open and close, and cause the upper limit rod 63 of the hinge part of the scissor 61 to slide back and forth in the stroke groove 62. When the scissor 61 closes, it moves forward to cut the excess glass wool strip in front. When the scissor 61 opens, it moves backward so that the glass wool can fall down a certain distance and wait for the next cut, thus completing the cutting of the excess glass wool into segments.
