This models was introduced early January 2017 and satisfy the need for keder protection on the larger structure tents that is typically associated with the party and events rental industry in Europe and USA.
Measuring H: 120 mm, W: 100 mm and D: 13 mm, the CF110 is the largest model in the range made for 11 mm keder diameters. It is made for larger Clearspan tents and structures.
Unlike the smaller models, that completely cap the corner end of the panel, the CF110 can have textile continue where the keder end, which makes it independent of the panel length after the keder stop.
1. Protective edge
The coverfeed® models protects the edge of the textile leading up to the fitting by being covered inside the slit, so battering during installment is kept at a minimum and endurance at max.
2. The Ripple-slug©
The slug going inside the groove is rippled in diameter in order to flex properly, when turning corners in a tent frame’s ridge/ crown.
3. Fixture by screws
The coverfeed® KCF85 models is fixed by 5 chipboard screws, piercing through the textile, though not cutting the reinforcing threads inside the textile and compromising strength, making the fixture completely stable. The sockets are countersunk on the screw head side of the Coverfeed® to avoid uneven shapes.
4. Reinforced hole for pulling
The hole is designed to accomodate the stresses from pulling the tent with rope from one side of the frame to the other. The edge of the hole is bulging in surface, adding material, distributing the loads evenly over the surfaces.
5. The Spike
The pointy spike allows the keder, when inserted, to be kept in precise aligment to the whole fixture and at the same time solidifying the fixture.
6. Keder collar
The keder is protected by a 'collar' and fixed by the spike, avoiding exposure of the woven keder end and fragile leading edge of the textile.
Get all your components ready and within reach. In that way, installation will go faster and smoother.
2. Measure the cutout
30 mm from the back of the keder and in; 50 mm from top edge and down for the KCF85 model.
3. Make the cutout
Use large sharp scissors or Stanley knife. Note, that there are different measurements of cutout from model to model.
4. Drill hole in keder for spike
Use a 2 or 3 mm drill to make a cavity in which the spike will be lowered. Drill down in the center of the keder in the excess of 20 mm.
5. Lower the Coverfeed®
Insert the tent corner in between the slit of the coverfeed® and lower. Make the spike go down the cavity and lower all way down.
6. Toggle for proper fit
Make sure the coverfeed® fits and all cutout edges are hidden properly inside the coverfeed®.
7. Fix with 5 screws
Use stainless flathead countersunk chipboard screws in the length 10 mm (i.e. Bossard, BN 1426). Fix them in the suggested order to avoid wrinkles.
You’ve spent about 2 minutes and you will probably beat this time once you get the routine.

Keep it simple!
One of the main criterias, when we started out designing Coverfeeds®, was the whole attachment and installment problem. By analyzing the PVC vinyl fabrics used on most covers in the market, we used a lot of our membrane load and stretch experience from the sailmaking industry we are so familiar with and solved this with a simple chipboard screw.
The solution was to be simple, effective, low cost and only require existing familiar tools to be handled on any spot necessary in case of emergency repairs or retrofit.
Screws don't cut the structural yarns
By perforating the fabric with screws we do not actually cut over the yarns, but merely create a tiny hole in the water resistant membrane and thereby we do not reduce the strength of the textile at all.
On top, we have positioned at least two screws to go through the dense webbing of the keder, reinforcing the attachment from the loads of pulling ceilings over beams on ie. Clearspans.
Alternatively; If we had punched a hole and used ie. rivets or click solutions to assemble, we would have cut over a lot of yarns in a critical area with high loads, hence compromising the structural reliability essentially inviting damage to come by.
It can handle even the heavy pullers
We know membrane loads and with yachting sails and we are talking multiple tonnes in every corner. With tents it is 'only' still kilos or pounds since most still install ceilings by hand pulling from 2-3 persons across beams and Clearspans (OK, some use fork lifts or Oxes), essentially loading pressure with around 300 kilos at the most (in case they are all hanging freely in the air from the Coverfeed®).
Even the smallest of our models (KCF85) can take more than 600 kilos without breaking and our tests did'nt show permanent damage (wrinkles) to the textiles before 465 kilos, which is not standard loads.
Made of a versatile Nylon compound
The Coverfeed® models are manufactured by a compound based on a Nylon called Akulon®. The Akulon® polyamides represent the most versatile, well-rounded property profiles of any engineering plastics. It is the ideal material for high performance applications. Robustness, stiffness and high temperature capability make it highly suitable for automotive, electrical and demanding mechanical engineering applications.
High stiffness and strength
At elevated temperatures above 100°C Akulon® maintains good stiffness and strength. Although stiffness of Akulon® decreases sharply around the glass transition temperature (Tg), excellent levels of stiffness are still maintained to just below the melting point of the polymer, facilitating design of critical parts.
Akulon® offers outstanding resistance, even in dry as molded conditions, to impacts and shock, down to temperatures of -20°C (-4°F). This is why polyamides are preferred above other engineering plastics. At very low temperatures (-40°C or -40°F), fracture modes become brittle and parts can splinter under impact. For critical safety applications therefore impact modified grades are available in the Akulon® product family offering ductile and hence splinter free impact resistance down to extreme low temperatures.
High elongation at break
Akulon® can be designed with living hinges and snap fits and can accommodate inserts after molding with greatly reduced risk of cracking.
Proven for demanding applications
The combination of mechanical and thermal properties has enabled Akulon® to be used in replacing metals in many applications where durability, safety and part integrity can all be extremely important. Power tool housings, automotive engine intake manifolds, railroad ties, sports equipment bindings, are typical examples where performance, safety, and durability come together and where Akulon® provides the answer through superior and proven performance.
